*
- * This is a convenience wrapper for the
- * {@linkplain MethodHandles#loop(MethodHandle[][]) generic loop combinator}, and the constraints imposed on the {@code body}
- * handle follow directly from those described for the latter.
+ * The iterator itself will be determined by the evaluation of the {@code iterator} handle.
+ * Each value it produces will be stored in a loop iteration variable of type {@code T}.
+ *
+ * If the {@code body} handle returns a non-{@code void} type {@code V}, a leading loop iteration variable
+ * of that type is also present. This variable is initialized using the optional {@code init} handle,
+ * or to the {@linkplain #empty default value} of type {@code V} if that handle is {@code null}.
+ *
+ * In each iteration, the iteration variables are passed to an invocation of the {@code body} handle.
+ * A non-{@code void} value returned from the body (of type {@code V}) updates the leading
+ * iteration variable.
+ * The result of the loop handle execution will be the final {@code V} value of that variable
+ * (or {@code void} if there is no {@code V} variable).
+ *
+ * The following rules hold for the argument handles:
+ * - The {@code body} handle must not be {@code null}; its type must be of the form
+ * {@code (V T A...)V}, where {@code V} is non-{@code void}, or else {@code (T A...)void}.
+ * (In the {@code void} case, we assign the type {@code void} to the name {@code V},
+ * and we will write {@code (V T A...)V} with the understanding that a {@code void} type {@code V}
+ * is quietly dropped from the parameter list, leaving {@code (T A...)V}.)
+ *
- The parameter list {@code (V T A...)} of the body contributes to a list
+ * of types called the internal parameter list.
+ * It will constrain the parameter lists of the other loop parts.
+ *
- As a special case, if the body contributes only {@code V} and {@code T} types,
+ * with no additional {@code A} types, then the internal parameter list is extended by
+ * the argument types {@code A...} of the {@code iterator} handle; if it is {@code null} the
+ * single type {@code Iterable} is added and constitutes the {@code A...} list.
+ *
- If the iteration variable types {@code (V T)} are dropped from the internal parameter list, the resulting shorter
+ * list {@code (A...)} is called the external parameter list.
+ *
- The body return type {@code V}, if non-{@code void}, determines the type of an
+ * additional state variable of the loop.
+ * The body must both accept a leading parameter and return a value of this type {@code V}.
+ *
- If {@code init} is non-{@code null}, it must have return type {@code V}.
+ * Its parameter list (of some form {@code (A*)}) must be
+ * effectively identical
+ * to the external parameter list {@code (A...)}.
+ *
- If {@code init} is {@code null}, the loop variable will be initialized to its
+ * {@linkplain #empty default value}.
+ *
- If the {@code iterator} handle is non-{@code null}, it must have the return
+ * type {@code java.util.Iterator} or a subtype thereof.
+ * The iterator it produces when the loop is executed will be assumed
+ * to yield values which can be converted to type {@code T}.
+ *
- The parameter list of an {@code iterator} that is non-{@code null} (of some form {@code (A*)}) must be
+ * effectively identical to the external parameter list {@code (A...)}.
+ *
- If {@code iterator} is {@code null} it defaults to a method handle which behaves
+ * like {@link java.lang.Iterable#iterator()}. In that case, the internal parameter list
+ * {@code (V T A...)} must have at least one {@code A} type, and the default iterator
+ * handle parameter is adjusted to accept the leading {@code A} type, as if by
+ * the {@link MethodHandle#asType asType} conversion method.
+ * The leading {@code A} type must be {@code Iterable} or a subtype thereof, or an array type.
+ * This conversion step, done at loop construction time, must not throw a {@code WrongMethodTypeException}.
+ *
+ *
+ * The type {@code T} may be either a primitive or reference.
+ * Since type {@code Iterator} is erased in the method handle representation to the raw type {@code Iterator},
+ * the {@code iteratedLoop} combinator adjusts the leading argument type for {@code body} to {@code Object}
+ * as if by the {@link MethodHandle#asType asType} conversion method.
+ * Therefore, if an iterator of the wrong type appears as the loop is executed, runtime exceptions may occur
+ * as the result of dynamic conversions performed by {@link MethodHandle#asType(MethodType)}.
+ *
+ * The resulting loop handle's result type and parameter signature are determined as follows:
+ * - The loop handle's result type is the result type {@code V} of the body.
+ *
- The loop handle's parameter types are the types {@code (A...)},
+ * from the external parameter list.
+ *
*
* Here is pseudocode for the resulting loop handle. In the code, {@code V}/{@code v} represent the type / value of
* the loop variable as well as the result type of the loop; {@code T}/{@code t}, that of the elements of the
- * structure the loop iterates over, and {@code A}/{@code a}, that of the argument passed to the loop.
+ * structure the loop iterates over, and {@code A...}/{@code a...} represent arguments passed to the loop.
*
{@code
- * Iterator iterator(A); // defaults to Iterable::iterator
- * V init(A);
- * V body(T,V,A);
- * V iteratedLoop(A a) {
- * Iterator it = iterator(a);
- * V v = init(a);
+ * Iterator iterator(A...); // defaults to Iterable::iterator
+ * V init(A...);
+ * V body(V,T,A...);
+ * V iteratedLoop(A... a...) {
+ * Iterator it = iterator(a...);
+ * V v = init(a...);
* for (T t : it) {
- * v = body(t, v, a);
+ * v = body(v, t, a...);
* }
* return v;
* }
* }
*
- * The type {@code T} may be either a primitive or reference.
- * Since type {@code Iterator} is erased in the method handle representation to the raw type
- * {@code Iterator}, the {@code iteratedLoop} combinator adjusts the leading argument type for {@code body}

+ * The JVM converts integral values to boolean values using two

+ * to least-significant bit.
+ *
+ * The JNI documents specify that, at least for returning
+ * values from native methods, a Java boolean value is converted
+ * to the value-set 0..1 by first truncating to a byte (0..255 or
+ * maybe -128..127) and then testing against zero. Thus, Java
+ * booleans in non-Java data structures are by convention
+ * represented as 8-bit containers containing either zero (for
+ * false) or any non-zero value (for true).
+ *
+ *
Java booleans in the heap are also stored in bytes, but are
+ * strongly normalized to the value-set 0..1 (i.e., they are
+ * truncated to the least-significant bit).
+ *
+ *
The main reason for having different conventions for
+ * conversion is performance: Truncation to the least-significant
+ * bit can be usually implemented with fewer (machine)
+ * instructions than byte testing against zero.
+ *
+ *
A number of Unsafe methods load boolean values from the heap
+ * as bytes. Unsafe converts those values according to the JNI
+ * rules (i.e, using the "testing against zero" convention). The
+ * method {@code byte2bool} implements that conversion.
