//
// * A NamespaceDispatchInterceptor, which dispatch calls to existing
// namespace interceptors
// * A DomainDispatchInterceptor, which dispatch calls to existing domain
// interceptors.
//
// With the JMX Namespaces feature, the JMX MBeanServer is now structured
// as follows:
//
// The JMX MBeanServer delegates to a NamespaceDispatchInterceptor,
// which either dispatches to a namespace, or delegates to the
// DomainDispatchInterceptor (if the object name contained no namespace).
// The DomainDispatchInterceptor in turn either dispatches to a domain (if
// there is a JMXDomain for that domain) or delegates to the
// DefaultMBeanServerInterceptor (if there is no JMXDomain for that
// domain). This makes the following picture:
//
// JMX MBeanServer (outer shell)
// |
// |
// NamespaceDispatchInterceptor
// / \
// no namespace in object name? \
// / \
// / dispatch to namespace
// DomainDispatchInterceptor
// / \
// no JMXDomain for domain? \
// / \
// / dispatch to domain
// DefaultMBeanServerInterceptor
// /

* From the above, it is clear that the logic for getX on an MXBean is

* The above describes the logic for "plain" MXBeanLookup, represented

* might be a//m:m=m. In this case, we don't accept a reference to

* a//p:p=p we should convert this to just p:p=p. If productProxy is for
* a//b//p:p=p we should convert it to b//p:p=p. Conversely, if getProduct
* returns an ObjectName like b//p:p=p then we should convert it into a proxy

//
// RoutingProxies are client side objects which are used to narrow down
// into a namespace. They are used to perform ObjectName translation,
// adding the namespace to the routing ObjectName before sending it over
// to the source connection, and removing that prefix from results of
// queries, createMBean, registerMBean, and getObjectInstance.
// This translation is the opposite to that which is performed by
// NamespaceInterceptors.
//
// There is however a special case where routing proxies are used on the
// 'server' side to remove a namespace - rather than to add it:
// This the case of ClientContext.
// When an ObjectName like "jmx.context//c1=v1,c2=v2//D:k=v" reaches the
// jmx.context namespace, a routing proxy is used to remove the prefix
// c1=v1,c2=v2// from the routing objectname.
//
// For a RoutingProxy used in a narrowDownToNamespace operation, we have:
// targetNs="" // targetNS is the namespace 'to remove'
// sourceNS=<namespace-we-narrow-down-to> // namespace 'to add'
//
// For a RoutingProxy used in a ClientContext operation, we have:
// targetNs=<encoded-context> // context must be removed from object name
// sourceNs="" // nothing to add...
//
// Finally, in order to avoid too many layers of wrapping,
// RoutingConnectionProxy and RoutingServerProxy can be created through a
// factory method that can concatenate namespace paths in order to
// return a single RoutingProxy - rather than wrapping a RoutingProxy inside
// another RoutingProxy. See RoutingConnectionProxy.cd and
// RoutingServerProxy.cd
//
// The class hierarchy is as follows:
//
// RoutingMBeanServerConnection
// [abstract class for all routing interceptors,
// such as RoutingProxies and HandlerInterceptors]
// / \
// / \
// RoutingProxy HandlerInterceptor
// [base class for [base class for server side
// client-side objects used objects, created by
// in narrowDownTo] DispatchInterceptors]
// / \ | \
// RoutingConnectionProxy \ | NamespaceInterceptor
// [wraps MBeanServerConnection \ | [used to remove
// objects] \ | namespace prefix and
// RoutingServerProxy | wrap JMXNamespace]
// [wraps MBeanServer |
// Objects] |
// DomainInterceptor
// [used to wrap JMXDomain]
//
// RoutingProxies also differ from HandlerInterceptors in that they transform
// calls to MBeanServerConnection operations that do not have any parameters
// into a call to the underlying JMXNamespace MBean.
// So for instance a call to:
// JMXNamespaces.narrowDownToNamespace(conn,"foo").getDomains()
// is transformed into
// conn.getAttribute("foo//type=JMXNamespace","Domains");

package com.sun.jmx.namespace.serial;
import javax.management.ObjectInstance;
import javax.management.ObjectName;
/**
* An object that can rewrite ObjectNames contained in input/output
* parameters when entering/leaving a {@link javax.management.namespace
* namespace}.
* <p>When entering a {@link javax.management.namespace
* namespace}, the {@code namespace} prefix is stripped from
* ObjectNames contained in input parameters. When leaving a
* {@code namespace},
* the {@code namespace} prefix is prepended to the ObjectNames contained in
* the result parameters returned from that {@code namespace}.
* </p>
* <p>Objects that need to perform these operations usually use a
* {@code RewritingProcessor} for that purpose.<br>
* The {@code RewritingProcessor} allows a somewhat larger
* transformation in which part of a prefix {@link #newRewritingProcessor
* remove} can be replaced by another prefix {@link #newRewritingProcessor
* add}. The transformation described above correspond to the case where
* {@code remove} is the stripped {@link javax.management.namespace
* namespace} prefix (removed when entering the {@code namespace}) and
* {@code add} is the empty String {@code ""}.
* <br>
* It is interesting to note that {@link
* javax.management.JMXNamespaces#narrowToNamespace narrowToNamespace}
* operations use the inverse transformation (that is, {@code remove} is
* the empty String {@code ""} and {@code add} is the {@link
* javax.management.namespace namespace} prefix).
* <br>
* On a more general scale, {@link #rewriteInput rewriteInput} removes
* {@link #newRewritingProcessor remove} and the prepend {@link
* #newRewritingProcessor add}, and {@link #rewriteOutput rewriteOutput}
* does the opposite, removing {@link #newRewritingProcessor add}, and
* then adding {@link #newRewritingProcessor remove}.
* <br>
* An implementation of {@code RewritingProcessor} should make sure that
* <code>rewriteInput(rewriteOutput(x,clp),clp)</code> and
* <code>rewriteOutput(rewriteInput(x,clp),clp)</code> always return
* {@code x} or an exact clone of {@code x}.
* </p>
* <p>A default implementation of {@code RewritingProcessor} based on
* Java Object Serialization can be
* obtained from {@link #newRewritingProcessor newRewritingProcessor}.
* </p>
* <p>
* By default, the instances of {@code RewritingProcessor} returned by
* {@link #newRewritingProcessor newRewritingProcessor} will rewrite
* ObjectNames contained in instances of classes they don't know about by
* serializing and then deserializing such object instances. This will
* happen even if such instances don't - or can't contain ObjectNames,
* because the default implementation of {@code RewritingProcessor} will
* not be able to determine whether instances of such classes can/do contain
* instance of ObjectNames before serializing/deserializing them.
* </p>
* <p>If you are using custom classes that the default implementation of
* {@code RewritingProcessor} don't know about, it can be interesting to
* prevent an instance of {@code RewritingProcessor} to serialize/deserialize
* instances of such classes for nothing. In that case, you could customize
* the behavior of such a {@code RewritingProcessor} by wrapping it in a
* custom subclass of {@code RewritingProcessor} as shown below:
* <pre>
* public class MyRewritingProcessor extends RewritingProcessor {
* MyRewritingProcessor(String remove, String add) {
* this(RewritingProcessor.newRewritingProcessor(remove,add));
* }
* MyRewritingProcessor(RewritingProcessor delegate) {
* super(delegate);
* }
*
* <T> T rewriteInput(T input) {
* if (input == null) return null;
* if (MyClass.equals(input.getClass())) {
* // I know that MyClass doesn't contain any ObjectName
* return (T) input;
* }
* return super.rewriteInput(input);
* }
* <T> T rewriteOutput(T result) {
* if (result == null) return null;
* if (MyClass.equals(result.getClass())) {
* // I know that MyClass doesn't contain any ObjectName
* return (T) result;
* }
* return super.rewriteOutput(result);
* }
* }
* </pre>
* </p>
* <p>Such a subclass may also provide an alternate way of rewriting
* custom subclasses for which rewriting is needed - for instance:
* <pre>
* public class MyRewritingProcessor extends RewritingProcessor {
* MyRewritingProcessor(String remove, String add) {
* this(RewritingProcessor.newRewritingProcessor(remove,add));
* }
* MyRewritingProcessor(RewritingProcessor delegate) {
* super(delegate);
* }
*
* <T> T rewriteInput(T input) {
* if (input == null) return null;
* if (MyClass.equals(input.getClass())) {
* // I know that MyClass doesn't contain any ObjectName
* return (T) input;
* } else if (MyOtherClass.equals(input.getClass())) {
* // Returns a new instance in which ObjectNames have been
* // replaced.
* final ObjectName aname = ((MyOtherClass)input).getName();
* return (T) (new MyOtherClass(super.rewriteInput(aname)));
* }
* return super.rewriteInput(input,clp);
* }
* <T> T rewriteOutput(T result) {
* if (result == null) return null;
* if (MyClass.equals(result.getClass())) {
* // I know that MyClass doesn't contain any ObjectName
* return (T) result;
* } else if (MyOtherClass.equals(result.getClass())) {
* // Returns a new instance in which ObjectNames have been
* // replaced.
* final ObjectName aname = ((MyOtherClass)result).getName();
* return (T) (new MyOtherClass(super.rewriteOutput(aname)));
* }
* return super.rewriteOutput(result,clp);
* }
* }
* </pre>
* </p>
* <p>If your application only uses {@link javax.management.MXBean MXBeans},
* or MBeans using simple types, and doesn't define any custom subclass of
* {@link javax.management.Notification}, you should never write such
* such {@code RewitingProcessor} implementations.

/**
* <p>The textual description of an MBean or part of an MBean. This
* description is intended to be displayed to users to help them
* understand what the MBean does. Ultimately it will be the value of
* the {@code getDescription()} method of an {@link MBeanInfo}, {@link
* MBeanAttributeInfo}, or similar.</p>
*
* <p>This annotation applies to Standard MBean interfaces and to
* MXBean interfaces, as well as to MBean classes defined using the
* {@link MBean @MBean} or {@link MXBean @MXBean} annotations. For
* example, a Standard MBean might be defined like this:</p>
*
* <pre>
* <b>{@code @Description}</b>("Application configuration")
* public interface ConfigurationMBean {
* <b>{@code @Description}</b>("Cache size in bytes")
* public int getCacheSize();
* public void setCacheSize(int size);
*
* <b>{@code @Description}</b>("Last time the configuration was changed, " +
* "in milliseconds since 1 Jan 1970")
* public long getLastChangedTime();
*
* <b>{@code @Description}</b>("Save the configuration to a file")
* public void save(
* <b>{@code @Description}</b>("Optional name of the file, or null for the default name")
* String fileName);
* }
* </pre>
*
* <p>The {@code MBeanInfo} for this MBean will have a {@link
* MBeanInfo#getDescription() getDescription()} that is {@code
* "Application configuration"}. It will contain an {@code
* MBeanAttributeInfo} for the {@code CacheSize} attribute that is
* defined by the methods {@code getCacheSize} and {@code
* setCacheSize}, and another {@code MBeanAttributeInfo} for {@code
* LastChangedTime}. The {@link MBeanAttributeInfo#getDescription()
* getDescription()} for {@code CacheSize} will be {@code "Cache size
* in bytes"}. Notice that there is no need to add a
* {@code @Description} to both {@code getCacheSize} and {@code
* setCacheSize} - either alone will do. But if you do add a
* {@code @Description} to both, it must be the same.</p>
*
* <p>The {@code MBeanInfo} will also contain an {@link
* MBeanOperationInfo} where {@link
* MBeanOperationInfo#getDescription() getDescription()} is {@code
* "Save the configuration to a file"}. This {@code
* MBeanOperationInfo} will contain an {@link MBeanParameterInfo}
* where {@link MBeanParameterInfo#getDescription() getDescription()}
* is {@code "Optional name of the file, or null for the default
* name"}.</p>
*
* <p>The {@code @Description} annotation can also be applied to the
* public constructors of the implementation class. Continuing the
* above example, the {@code Configuration} class implementing {@code
* ConfigurationMBean} might look like this:</p>
*
* <pre>
* public class Configuration implements ConfigurationMBean {
* <b>{@code @Description}</b>("A Configuration MBean with the default file name")
* public Configuration() {
* this(DEFAULT_FILE_NAME);
* }
*
* <b>{@code @Description}</b>("A Configuration MBean with a specified file name")
* public Configuration(
* <b>{@code @Description}</b>("Name of the file the configuration is stored in")
* String fileName) {...}
* ...
* }
* </pre>
*
* <p>The {@code @Description} annotation also works in MBeans that
* are defined using the {@code @MBean} or {@code @MXBean} annotation
* on classes. Here is an alternative implementation of {@code
* Configuration} that does not use an {@code ConfigurationMBean}
* interface.</p>
*
* <pre>
* <b>{@code @MBean}</b>
* <b>{@code @Description}</b>("Application configuration")
* public class Configuration {
* <b>{@code @Description}</b>("A Configuration MBean with the default file name")
* public Configuration() {
* this(DEFAULT_FILE_NAME);
* }
*
* <b>{@code @Description}</b>("A Configuration MBean with a specified file name")
* public Configuration(
* <b>{@code @Description}</b>("Name of the file the configuration is stored in")
* String fileName) {...}
*
* <b>{@code @ManagedAttribute}</b>
* <b>{@code @Description}</b>("Cache size in bytes")
* public int getCacheSize() {...}
* <b>{@code @ManagedAttribute}</b>
* public void setCacheSize(int size) {...}
*
* <b>{@code @ManagedOperation}</b>
* <b>{@code @Description}</b>("Last time the configuration was changed, " +
* "in milliseconds since 1 Jan 1970")
* public long getLastChangedTime() {...}
*
* <b>{@code @ManagedOperation}</b>
* <b>{@code @Description}</b>("Save the configuration to a file")
* public void save(
* <b>{@code @Description}</b>("Optional name of the file, or null for the default name")
* String fileName) {...}

/**
* <p>Annotation that adds fields to a {@link Descriptor}. This can be the
* Descriptor for an MBean, or for an attribute, operation, or constructor
* in an MBean, or for a parameter of an operation or constructor.</p>
*
* <p>Consider this Standard MBean interface, for example:</p>
*
* <pre>
* public interface CacheControlMBean {
* <b>&#64;DescriptorFields("units=bytes")</b>
* public long getCacheSize();
* }
* </pre>
*
* <p>When a Standard MBean is made using this interface, the usual rules
* mean that it will have an attribute called {@code CacheSize} of type
* {@code long}. The {@code DescriptorFields} annotation will ensure
* that the {@link MBeanAttributeInfo} for this attribute will have a
* {@code Descriptor} that has a field called {@code units} with
* corresponding value {@code bytes}.</p>
*
* <p>Similarly, if the interface looks like this:</p>
*
* <pre>
* public interface CacheControlMBean {
* <b>&#64;DescriptorFields({"units=bytes", "since=1.5"})</b>
* public long getCacheSize();
* }
* </pre>
*
* <p>then the resulting {@code Descriptor} will contain the following
* fields:</p>
*
* <table border="2">
* <tr><th>Name</th><th>Value</th></tr>
* <tr><td>units</td><td>"bytes"</td></tr>
* <tr><td>since</td><td>"1.5"</td></tr>
* </table>
*
* <p>The {@code @DescriptorFields} annotation can be applied to:</p>
*
* <ul>
* <li>a Standard MBean or MXBean interface;
* <li>a method in such an interface;
* <li>a parameter of a method in a Standard MBean or MXBean interface
* when that method is an operation (not a getter or setter for an attribute);
* <li>a public constructor in the class that implements a Standard MBean
* or MXBean;
* <li>a parameter in such a constructor.
* </ul>
*
* <p>Other uses of the annotation will either fail to compile or be
* ignored.</p>
*
* <p>Interface annotations are checked only on the exact interface
* that defines the management interface of a Standard MBean or an
* MXBean, not on its parent interfaces. Method annotations are
* checked only in the most specific interface in which the method
* appears; in other words, if a child interface overrides a method
* from a parent interface, only {@code @DescriptorFields} annotations in
* the method in the child interface are considered.
*
* <p>The Descriptor fields contributed in this way must be consistent
* with each other and with any fields contributed by {@link
* DescriptorKey &#64;DescriptorKey} annotations. That is, two
* different annotations, or two members of the same annotation, must
* not define a different value for the same Descriptor field. Fields
* from annotations on a getter method must also be consistent with
* fields from annotations on the corresponding setter method.</p>
*
* <p>The Descriptor resulting from these annotations will be merged
* with any Descriptor fields provided by the implementation, such as
* the <a href="Descriptor.html#immutableInfo">{@code
* immutableInfo}</a> field for an MBean. The fields from the annotations
* must be consistent with these fields provided by the implementation.</p>
*
* <h4>{@literal @DescriptorFields and @DescriptorKey}</h4>
*
* <p>The {@link DescriptorKey @DescriptorKey} annotation provides
* another way to use annotations to define Descriptor fields.
* <code>&#64;DescriptorKey</code> requires more work but is also more
* robust, because there is less risk of mistakes such as misspelling
* the name of the field or giving an invalid value.
* <code>&#64;DescriptorFields</code> is more convenient but includes
* those risks. <code>&#64;DescriptorFields</code> is more
* appropriate for occasional use, but for a Descriptor field that you
* add in many places, you should consider a purpose-built annotation
* using <code>&#64;DescriptorKey</code>.

import javax.management.openmbean.CompositeData;
/**
* <p>A customizable exception that has an optional error code string and
* payload. By using this exception in an MBean, you can avoid requiring
* clients of the MBean to have custom exception classes.</p>
*
* <p>An instance of this class has an optional {@linkplain #getErrorCode()
* error code}, and an optional {@linkplain #getUserData() payload} known as
* {@code userData}. This allows you to distinguish between different
* sorts of exception while still using this class for all of them.</p>
*
* <p>To produce a suitable {@code userData}, it is often simplest to use
* the MXBean framework. For example, suppose you want to convey a severity
* and a subsystem with your exception, which are respectively an int and a
* String. You could define a class like this:</p>
*
* <pre>
* public class ExceptionDetails {
* private final int severity;
* private final String subsystem;
*
* {@link java.beans.ConstructorProperties &#64;ConstructorProperties}(<!--
* -->{"severity", "subsystem"})
* public ExceptionDetails(int severity, String subsystem) {
* this.severity = severity;
* this.subsystem = subsystem;
* }
*
* public int getSeverity() {
* return severity;
* }
*
* public String getSubsystem() {
* return subsystem;
* }
* }
* </pre>
*
* <p>Then you can get the MXBean framework to transform {@code ExceptionDetails}
* into {@link CompositeData} like this:</p>
*
* <pre>
* static final <!--
* -->{@link javax.management.openmbean.MXBeanMapping MXBeanMapping} <!--
* -->exceptionDetailsMapping = <!--
* -->{@link javax.management.openmbean.MXBeanMappingFactory#DEFAULT
* MXBeanMappingFactory.DEFAULT}.mappingForType(
* ExceptionDetails.class, MXBeanMappingFactory.DEFAULT);
*
* public static GenericMBeanException newGenericMBeanException(
* String message, String errorCode, int severity, String subsystem) {
* ExceptionDetails details = new ExceptionDetails(severity, subsystem);
* CompositeData userData = (CompositeData)
* exceptionDetailsMapping.toOpenValue(details);
* return new GenericMBeanException(
* message, errorCode, userData, (Throwable) null);
* }
*
* ...
* throw newGenericMBeanException(message, errorCode, 25, "foosystem");
* </pre>
*
* <p>A client that knows the {@code ExceptionDetails} class can convert
* back from the {@code userData} of a {@code GenericMBeanException}
* that was generated as above:</p>
*
* <pre>
* ...
* try {
* mbeanProxy.foo();
* } catch (GenericMBeanException e) {
* CompositeData userData = e.getUserData();
* ExceptionDetails details = (ExceptionDetails)
* exceptionDetailsMapping.fromOpenValue(userData);
* System.out.println("Exception Severity: " + details.getSeverity());
* }
* ...
* </pre>
*
* <p>The Descriptor field <a href="Descriptor.html#exceptionErrorCodes"><!--
* -->exceptionErrorCodes</a> can be used to specify in the
* {@link MBeanOperationInfo} for an operation what the possible
* {@linkplain #getErrorCode() error codes} are when that operation throws
* {@code GenericMBeanException}. It can also be used in an {@link
* MBeanConstructorInfo} or {@link MBeanAttributeInfo} to specify what the
* possible error codes are for {@code GenericMBeanException} when invoking
* that constructor or getting that attribute, respectively. The field
* <a href="Descriptor.html#setExceptionErrorCodes"><!--
* -->setExceptionErrorCodes</a> can be used to specify what the possible
* error codes are when setting an attribute.</p>
*
* <p>You may want to use the {@link DescriptorKey &#64;DescriptorKey} facility
* to define annotations that allow you to specify the error codes. If you
* define...</p>
*
* <pre>
* {@link java.lang.annotation.Documented &#64;Documented}
* {@link java.lang.annotation.Target &#64;Target}(ElementType.METHOD)
* {@link java.lang.annotation.Retention &#64;Retention}(RetentionPolicy.RUNTIME)
* public &#64;interface ErrorCodes {
* &#64;DescriptorKey("exceptionErrorCodes")
* String[] value();
* }
* </pre>
*
* <p>...then you can write MBean interfaces like this...</p>
*
* <pre>
* public interface FooMBean { // or FooMXBean
* &#64;ErrorCodes({"com.example.bad", "com.example.worse"})
* public void foo() throws GenericMBeanException;
* }
* </pre>
*
* <p>The Descriptor field <a href="Descriptor.html#exceptionUserDataTypes"><!--
* -->exceptionUserDataTypes</a> can be used to specify in the
* {@link MBeanOperationInfo} for an operation what the possible types of
* {@linkplain #getUserData() userData} are when that operation throws
* {@code GenericMBeanException}. It is an array of
* {@link javax.management.openmbean.CompositeType CompositeType} values
* describing the possible {@link CompositeData} formats. This field can also be used
* in an {@link MBeanConstructorInfo} or {@link MBeanAttributeInfo} to specify
* the possible types of user data for {@code GenericMBeanException} when
* invoking that constructor or getting that attribute, respectively. The
* field
* <a href="Descriptor.html#setExceptionUserDataTypes">setExceptionUserDataTypes</a>
* can be used to specify the possible types of user data for exceptions when
* setting an attribute. If a Descriptor has both {@code exceptionErrorCodes}
* and {@code exceptionUserDataTypes} then the two arrays should be the
* same size; each pair of corresponding elements describes one kind
* of exception. Similarly for {@code setExceptionErrorCodes} and {@code
* setExceptionUserDataTypes}.
*
*
* <h4>Serialization</h4>
*
* <p>For compatibility reasons, instances of this class are serialized as
* instances of {@link MBeanException}. Special logic in that class converts
* them back to instances of this class at deserialization time. If the
* serialized object is deserialized in an earlier version of the JMX API
* that does not include this class, then it will appear as just an {@code
* MBeanException} and the error code or userData will not be available.</p>

* contained in the {@code MBeanInfo}.</p>
*
* <p>Here is how the description {@code this.getDescription()} is
* localized.</p>
*
* <p>First, if the {@linkplain #getDescriptor() descriptor}
* of this {@code MBeanInfo} contains a field <code><a
* href="Descriptor.html#locale">"locale"</a></code>, and the value of
* the field is the same as {@code locale.toString()}, then this {@code
* MBeanInfo} is returned. Otherwise, localization proceeds as follows,
* and the {@code "locale"} field in the returned {@code MBeanInfo} will
* be {@code locale.toString()}.
*
* <p>A <em>{@code className}</em> is determined. If this
* {@code MBeanInfo} contains a descriptor with the field
* <a href="Descriptor.html#interfaceClassName">{@code
* "interfaceClassName"}</a>, then the value of that field is the
* {@code className}. Otherwise, it is {@link #getClassName()}.
* Everything before the last period (.) in the {@code className} is
* the <em>{@code package}</em>, and everything after is the <em>{@code
* simpleClassName}</em>. (If there is no period, then the {@code package}
* is empty and the {@code simpleClassName} is the same as the {@code
* className}.)</p>
*
* <p>A <em>{@code resourceKey}</em> is determined. If this {@code
* MBeanInfo} contains a {@linkplain MBeanInfo#getDescriptor() descriptor}
* with a field {@link JMX#DESCRIPTION_RESOURCE_KEY_FIELD
* "descriptionResourceKey"}, the value of the field is
* the {@code resourceKey}. Otherwise, the {@code resourceKey} is {@code
* simpleClassName + ".mbean"}.</p>
*
* <p>A <em>{@code resourceBundleBaseName}</em> is determined. If
* this {@code MBeanInfo} contains a descriptor with a field {@link
* JMX#DESCRIPTION_RESOURCE_BUNDLE_BASE_NAME_FIELD
* "descriptionResourceBundleBaseName"}, the value of the field
* is the {@code resourceBundleBaseName}. Otherwise, the {@code
* resourceBundleBaseName} is {@code package + ".MBeanDescriptions"}.
*
* <p>Then, a {@link java.util.ResourceBundle ResourceBundle} is
* determined, using<br> {@link java.util.ResourceBundle#getBundle(String,
* Locale, ClassLoader) ResourceBundle.getBundle(resourceBundleBaseName,
* locale, loader)}. If this succeeds, and if {@link
* java.util.ResourceBundle#getString(String) getString(resourceKey)}
* returns a string, then that string is the localized description.
* Otherwise, the original description is unchanged.</p>
*
* <p>A localized description for an {@code MBeanAttributeInfo} is
* obtained similarly. The default {@code resourceBundleBaseName}
* is the same as above. The default description and the
* descriptor fields {@code "descriptionResourceKey"} and {@code
* "descriptionResourceBundleBaseName"} come from the {@code
* MBeanAttributeInfo} rather than the {@code MBeanInfo}. If the
* attribute's {@linkplain MBeanFeatureInfo#getName() name} is {@code
* Foo} then its default {@code resourceKey} is {@code simpleClassName +
* ".attribute.Foo"}.</p>
*
* <p>Similar rules apply for operations, constructors, and notifications.
* If the name of the operation, constructor, or notification is {@code
* Foo} then the default {@code resourceKey} is respectively {@code
* simpleClassName + ".operation.Foo"}, {@code simpleClassName +
* ".constructor.Foo"}, or {@code simpleClassName + ".notification.Foo"}.
* If two operations or constructors have the same name (overloading) then
* they have the same default {@code resourceKey}; if different localized
* descriptions are needed then a non-default key must be supplied using
* {@code "descriptionResourceKey"}.</p>
*
* <p>Similar rules also apply for descriptions of parameters ({@link
* MBeanParameterInfo}). The default {@code resourceKey} for a parameter
* whose {@linkplain MBeanFeatureInfo#getName() name} is {@code
* Bar} in an operation or constructor called {@code Foo} is {@code
* simpleClassName + ".operation.Foo.Bar"} or {@code simpleClassName +
* ".constructor.Foo.Bar"} respectively.</p>
*
* <h4>Example</h4>
*
* <p>Suppose you have an MBean defined by these two Java source files:</p>
*
* <pre>
* // ConfigurationMBean.java
* package com.example;
* public interface ConfigurationMBean {
* public String getName();
* public void save(String fileName);
* }
*
* // Configuration.java
* package com.example;
* public class Configuration implements ConfigurationMBean {
* public Configuration(String defaultName) {
* ...
* }
* ...
* }
* </pre>
*
* <p>Then you could define the default descriptions for the MBean, by
* including a resource bundle called {@code com/example/MBeanDescriptions}
* with the compiled classes. Most often this is done by creating a file
* {@code MBeanDescriptions.properties} in the same directory as {@code
* ConfigurationMBean.java}. Make sure that this file is copied into the
* same place as the compiled classes; in typical build environments that
* will be true by default.</p>
*
* <p>The file {@code com/example/MBeanDescriptions.properties} might
* look like this:</p>
*
* <pre>
* # Description of the MBean
* ConfigurationMBean.mbean = Configuration manager
*
* # Description of the Name attribute
* ConfigurationMBean.attribute.Name = The name of the configuration
*
* # Description of the save operation
* ConfigurationMBean.operation.save = Save the configuration to a file
*
* # Description of the parameter to the save operation.
* # Parameter names from the original Java source are not available,
* # so the default names are p1, p2, etc. If the names were available,
* # this would be ConfigurationMBean.operation.save.fileName
* ConfigurationMBean.operation.save.p1 = The name of the file
*
* # Description of the constructor. The default name of a constructor is
* # its fully-qualified class name.
* ConfigurationMBean.constructor.com.example.Configuration = <!--
* -->Constructor with name of default file
* # Description of the constructor parameter.
* ConfigurationMBean.constructor.com.example.Configuration.p1 = <!--
* -->Name of the default file
* </pre>
*
* <p>Starting with this file, you could create descriptions for the French
* locale by creating {@code com/example/MBeanDescriptions_fr.properties}.
* The keys in this file are the same as before but the text has been
* translated:
*
* <pre>
* ConfigurationMBean.mbean = Gestionnaire de configuration
*
* ConfigurationMBean.attribute.Name = Le nom de la configuration
*
* ConfigurationMBean.operation.save = Sauvegarder la configuration <!--
* -->dans un fichier
*
* ConfigurationMBean.operation.save.p1 = Le nom du fichier
*
* ConfigurationMBean.constructor.com.example.Configuration = <!--
* -->Constructeur avec nom du fichier par d&eacute;faut
* ConfigurationMBean.constructor.com.example.Configuration.p1 = <!--

* MBean Server.</p>
*
* <h4 id="injection">Resource injection</h4>
*
* <p>As an alternative to implementing {@code MBeanRegistration}, if all that
* is needed is the MBean Server or ObjectName then an MBean can use
* <em>resource injection</em>.</p>
*
* <p>If a field in the MBean object has type {@link ObjectName} and has
* the {@link javax.annotation.Resource &#64;Resource} annotation,
* then the {@code ObjectName} under which the MBean is registered is
* assigned to that field during registration. Likewise, if a field has type
* {@link MBeanServer} and the <code>&#64;Resource</code> annotation, then it will
* be set to the {@code MBeanServer} in which the MBean is registered.</p>
*
* <p>For example:</p>
*
* <pre>
* public Configuration implements ConfigurationMBean {
* &#64;Resource
* private volatile MBeanServer mbeanServer;
* &#64;Resource
* private volatile ObjectName objectName;
* ...
* void unregisterSelf() throws Exception {
* mbeanServer.unregisterMBean(objectName);
* }
* }
* </pre>
*
* <p>Resource injection can also be used on fields of type
* {@link SendNotification} to simplify notification sending. Such a field
* will get a reference to an object of type {@code SendNotification} when
* the MBean is registered, and it can use this reference to send notifications.
* For example:</p>
*
* <pre>
* public Configuration implements ConfigurationMBean {
* &#64;Resource
* private volatile SendNotification sender;
* ...
* private void updated() {
* Notification n = new Notification(...);
* sender.sendNotification(n);
* }
* }
* </pre>
*
* <p>(Listeners may be invoked in the same thread as the caller of
* {@code sender.sendNotification}.)</p>
*
* <p>A field to be injected must not be static. It is recommended that
* such fields be declared {@code volatile}.</p>
*
* <p>It is also possible to use the <code>&#64;Resource</code> annotation on
* methods. Such a method must have a {@code void} return type and a single
* argument of the appropriate type, for example {@code ObjectName}.</p>
*
* <p>Any number of fields and methods may have the <code>&#64;Resource</code>
* annotation. All fields and methods with type {@code ObjectName}
* (for example) will receive the same {@code ObjectName} value.</p>
*
* <p>Resource injection is available for all types of MBeans, not just
* Standard MBeans.</p>
*
* <p>If an MBean implements the {@link DynamicWrapperMBean} interface then
* resource injection happens on the object returned by that interface's
* {@link DynamicWrapperMBean#getWrappedObject() getWrappedObject()} method
* rather than on the MBean object itself.
*
* <p>Resource injection happens after the {@link #preRegister preRegister}
* method is called (if any), and before the MBean is actually registered
* in the MBean Server. If a <code>&#64;Resource</code> method throws
* an exception, the effect is the same as if {@code preRegister} had
* thrown the exception. In particular it will prevent the MBean from being
* registered.</p>
*
* <p>Resource injection can be used on a field or method where the type
* is a parent of the injected type, if the injected type is explicitly
* specified in the <code>&#64;Resource</code> annotation. For example:</p>
*
* <pre>
* &#64;Resource(type = MBeanServer.class)
* private volatile MBeanServerConnection mbsc;
* </pre>
*
* <p>Formally, suppose <em>R</em> is the type in the <code>&#64;Resource</code>
* annotation and <em>T</em> is the type of the method parameter or field.
* Then one of <em>R</em> and <em>T</em> must be a subtype of the other
* (or they must be the same type). Injection happens if this subtype
* is {@code MBeanServer}, {@code ObjectName}, or {@code SendNotification}.
* Otherwise the <code>&#64;Resource</code> annotation is ignored.</p>
*
* <p>Resource injection in MBeans is new in version 2.0 of the JMX API.</p>

<p>Alternatively, you can define a custom mapping for your recursive

<h3 id="custom">Custom MXBean type mappings</h3>
<p>You can augment or replace the default type mappings described
above with custom mappings. An example appears in the
documentation for {@link MXBeanMapping}.</p>
<p>If an MXBean uses custom mappings, then an MXBean proxy for
that MXBean must use the same mappings for correct behavior.
This requires more careful synchronization between client and
server than is necessary with the default mappings. For example
it typically requires the client to have the same implementation
of any {@link MXBeanMapping} subclasses as the server. For this
reason, custom mappings should be avoided if possible.</p>
<p>Every MXBean has an associated {@link MXBeanMappingFactory}.
Call this <code><em>f</em></code>. Then every type that appears
in that MXBean has an associated {@link MXBeanMapping}
determined by <code><em>f</em></code>. If the type is
<code><em>J</em></code>, say, then the mapping is {@link
MXBeanMappingFactory#mappingForType
<em>f</em>.mappingForType}<code>(<em>J</em>,
<em>f</em>)</code>.</p>
<p>The {@code MXBeanMappingFactory} <code><em>f</em></code> for an
MXBean is determined as follows.</p>
<ul>
<li><p>If a {@link JMX.MBeanOptions} argument is supplied to
the {@link StandardMBean} constructor that makes an MXBean,
or to the {@link JMX#newMBeanProxy(MBeanServerConnection,
ObjectName, Class, JMX.MBeanOptions) JMX.newMBeanProxy}
method, and the {@code MBeanOptions} object defines a non-null
{@code MXBeanMappingFactory}, then that is the value of
<code><em>f</em></code>.</p></li>
<li><p>Otherwise, if the MXBean interface has an {@link
MXBeanMappingFactoryClass} annotation, then that annotation
must identify a subclass of {@code MXBeanMappingFactory}
with a no-argument constructor. Then
<code><em>f</em></code> is the result of calling this
constructor. If the class does not have a no-argument
constructor, or if calling the constructor produces an
exception, then the MXBean is invalid and an attempt to
register it in the MBean Server will produce a {@link
NotCompliantMBeanException}.</p>
<p>This annotation is not inherited from any parent
interfaces. If an MXBean interface has this annotation,
then usually any MXBean subinterfaces must repeat the same
annotation for correct behavior.</p></li>
<li><p>Otherwise, if the package in which the MXBean interface
appears has an {@code MXBeanMappingFactoryClass} annotation,
then <code><em>f</em></code> is determined as if that
annotation appeared on the MXBean interface.</p></li>
<li><p>Otherwise, <code><em>f</em></code> is the default mapping
factory, {@link MXBeanMappingFactory#DEFAULT}.</p></li>
</ul>
<p>The default mapping factory recognizes the {@link
MXBeanMappingClass} annotation on a class or interface. If
<code><em>J</em></code> is a class or interface that has such an
annotation, then the {@code MXBeanMapping} for
<code><em>J</em></code> produced by the default mapping factory
will be determined by the value of the annotation as described
in its {@linkplain MXBeanMappingClass documentation}.</p>
