/**
|
|
* An <code>RMIClientSocketFactory</code> instance is used by the RMI runtime
|
|
* in order to obtain client sockets for RMI calls. A remote object can be
|
|
* associated with an <code>RMIClientSocketFactory</code> when it is
|
|
* created/exported via the constructors or <code>exportObject</code> methods
|
|
* of <code>java.rmi.server.UnicastRemoteObject</code> and
|
|
* <code>java.rmi.activation.Activatable</code> .
|
|
*
|
|
* <p>An <code>RMIClientSocketFactory</code> instance associated with a remote
|
|
* object will be downloaded to clients when the remote object's reference is
|
|
* transmitted in an RMI call. This <code>RMIClientSocketFactory</code> will
|
|
* be used to create connections to the remote object for remote method calls.
|
|
*
|
|
* <p>An <code>RMIClientSocketFactory</code> instance can also be associated
|
|
* with a remote object registry so that clients can use custom socket
|
|
* communication with a remote object registry.
|
|
*
|
|
* <p>An implementation of this interface should be serializable and
|
|
* should implement {@link Object#equals} to return <code>true</code> when
|
|
* passed an instance that represents the same (functionally equivalent)
|
|
* client socket factory, and <code>false</code> otherwise (and it should also
|
|
* implement {@link Object#hashCode} consistently with its
|
|
* <code>Object.equals</code> implementation).
