+/**
+ * This class is the abstract superclass of all actual
+ * implementations of the Abstract Window Toolkit. Subclasses of
+ * <code>Toolkit</code> are used to bind the various components
+ * to particular native toolkit implementations.
+ * <p>
+ * Many GUI operations may be performed asynchronously. This
+ * means that if you set the state of a component, and then
+ * immediately query the state, the returned value may not yet
+ * reflect the requested change. This includes, but is not
+ * limited to:
+ * <ul>
+ * <li>Scrolling to a specified position.
+ * <br>For example, calling <code>ScrollPane.setScrollPosition</code>
+ * and then <code>getScrollPosition</code> may return an incorrect
+ * value if the original request has not yet been processed.
+ * <p>
+ * <li>Moving the focus from one component to another.
+ * <br>For more information, see
+ * <a href="http://java.sun.com/docs/books/tutorial/uiswing/misc/focus.html#transferTiming">Timing
+ * Focus Transfers</a>, a section in
+ * <a href="http://java.sun.com/docs/books/tutorial/uiswing/">The Swing
+ * Tutorial</a>.
+ * <p>
+ * <li>Making a top-level container visible.
+ * <br>Calling <code>setVisible(true)</code> on a <code>Window</code>,
+ * <code>Frame</code> or <code>Dialog</code> may occur
+ * asynchronously.
+ * <p>
+ * <li>Setting the size or location of a top-level container.
+ * <br>Calls to <code>setSize</code>, <code>setBounds</code> or
+ * <code>setLocation</code> on a <code>Window</code>,
+ * <code>Frame</code> or <code>Dialog</code> are forwarded
+ * to the underlying window management system and may be
+ * ignored or modified. See {@link java.awt.Window} for
+ * more information.
+ * </ul>
+ * <p>
+ * Most applications should not call any of the methods in this
+ * class directly. The methods defined by <code>Toolkit</code> are
+ * the "glue" that joins the platform-independent classes in the
+ * <code>java.awt</code> package with their counterparts in
+ * <code>java.awt.peer</code>. Some methods defined by
+ * <code>Toolkit</code> query the native operating system directly.

corrects a mis-named public method in the Isolate class. I've renamed

+ * Array holds static helper functions that allow you to create and

+ * conversions, but throw {@link IllegalArgumentException} if you attempt
+ * a narrowing conversion. Also, when accessing primitive arrays, this
+ * class performs object wrapping and unwrapping as necessary.<p>
+ *
+ * <B>Note:</B> This class returns and accepts types as Classes, even
+ * primitive types; there are Class types defined that represent each
+ * different primitive type. They are <code>java.lang.Boolean.TYPE,
+ * java.lang.Byte.TYPE,</code>, also available as <code>boolean.class,
+ * byte.class</code>, etc. These are not to be confused with the
+ * classes <code>java.lang.Boolean, java.lang.Byte</code>, etc., which are
+ * real classes. Note also that the shorthand <code>Object[].class</code>
+ * is a convenient way to get array Classes.<p>
+ *
+ * <B>Performance note:</B> This class performs best when it does not have
+ * to convert primitive types. The further along the chain it has to convert,
+ * the worse performance will be. You're best off using the array as whatever
+ * type it already is, and then converting the result. You will do even
+ * worse if you do this and use the generic set() function.

-/**
- * The Field class represents a member variable of a class. It also allows
- * dynamic access to a member, via reflection. This works for both
- * static and instance fields. Operations on Field objects know how to
- * do widening conversions, but throw {@link IllegalArgumentException} if
- * a narrowing conversion would be necessary. You can query for information
- * on this Field regardless of location, but get and set access may be limited
- * by Java language access controls. If you can't do it in the compiler, you
- * can't normally do it here either.<p>
- *
- * <B>Note:</B> This class returns and accepts types as Classes, even
- * primitive types; there are Class types defined that represent each
- * different primitive type. They are <code>java.lang.Boolean.TYPE,
- * java.lang.Byte.TYPE,</code>, also available as <code>boolean.class,
- * byte.class</code>, etc. These are not to be confused with the
- * classes <code>java.lang.Boolean, java.lang.Byte</code>, etc., which are
- * real classes.<p>
- *
- * Also note that this is not a serializable class. It is entirely feasible
- * to make it serializable using the Externalizable interface, but this is
- * on Sun, not me.

-/**
- * The Constructor class represents a constructor of a class. It also allows
- * dynamic creation of an object, via reflection. Invocation on Constructor
- * objects knows how to do widening conversions, but throws
- * {@link IllegalArgumentException} if a narrowing conversion would be
- * necessary. You can query for information on this Constructor regardless
- * of location, but construction access may be limited by Java language
- * access controls. If you can't do it in the compiler, you can't normally
- * do it here either.<p>
- *
- * <B>Note:</B> This class returns and accepts types as Classes, even
- * primitive types; there are Class types defined that represent each
- * different primitive type. They are <code>java.lang.Boolean.TYPE,
- * java.lang.Byte.TYPE,</code>, also available as <code>boolean.class,
- * byte.class</code>, etc. These are not to be confused with the
- * classes <code>java.lang.Boolean, java.lang.Byte</code>, etc., which are
- * real classes.<p>
- *
- * Also note that this is not a serializable class. It is entirely feasible
- * to make it serializable using the Externalizable interface, but this is
- * on Sun, not me.

-/**
- * A secure class loader that can load classes and resources from
- * multiple locations. Given an array of <code>URL</code>s this class
- * loader will retrieve classes and resources by fetching them from
- * possible remote locations. Each <code>URL</code> is searched in
- * order in which it was added. If the file portion of the
- * <code>URL</code> ends with a '/' character then it is interpreted
- * as a base directory, otherwise it is interpreted as a jar file from
- * which the classes/resources are resolved.
- *
- * <p>New instances can be created by two static
- * <code>newInstance()</code> methods or by three public
- * contructors. Both ways give the option to supply an initial array
- * of <code>URL</code>s and (optionally) a parent classloader (that is
- * different from the standard system class loader).</p>
- *
- * <p>Normally creating a <code>URLClassLoader</code> throws a
- * <code>SecurityException</code> if a <code>SecurityManager</code> is
- * installed and the <code>checkCreateClassLoader()</code> method does
- * not return true. But the <code>newInstance()</code> methods may be
- * used by any code as long as it has permission to acces the given
- * <code>URL</code>s. <code>URLClassLoaders</code> created by the
- * <code>newInstance()</code> methods also explicitly call the
- * <code>checkPackageAccess()</code> method of
- * <code>SecurityManager</code> if one is installed before trying to
- * load a class. Note that only subclasses of
- * <code>URLClassLoader</code> can add new URLs after the
- * URLClassLoader had been created. But it is always possible to get
- * an array of all URLs that the class loader uses to resolve classes
- * and resources by way of the <code>getURLs()</code> method.</p>
- *
- * <p>Open issues:
- * <ul>
- *
- * <li>Should the URLClassLoader actually add the locations found in
- * the manifest or is this the responsibility of some other
- * loader/(sub)class? (see <a
- * href="http://java.sun.com/products/jdk/1.4/docs/guide/extensions/spec.html">
- * Extension Mechanism Architecture - Bundles Extensions</a>)</li>
- *
- * <li>How does <code>definePackage()</code> and sealing work
- * precisely?</li>

+
+
+Provides reference-object classes, which support a limited degree of
+interaction with the garbage collector. A program may use a reference object
+to maintain a reference to some other object in such a way that the latter
+object may still be reclaimed by the collector. A program may also arrange to
+be notified some time after the collector has determined that the reachability
+of a given object has changed.
+
+
+<h2>Package Specification</h2>
+
+A <em>reference object</em> encapsulates a reference to some other object so
+that the reference itself may be examined and manipulated like any other
+object. Three types of reference objects are provided, each weaker than the
+last: <em>soft</em>, <em>weak</em>, and <em>phantom</em>. Each type
+corresponds to a different level of reachability, as defined below. Soft
+references are for implementing memory-sensitive caches, weak references are
+for implementing canonicalizing mappings that do not prevent their keys (or
+values) from being reclaimed, and phantom references are for scheduling
+pre-mortem cleanup actions in a more flexible way than is possible with the
+Java finalization mechanism.
+
+<p> Each reference-object type is implemented by a subclass of the abstract
+base <code>{@link java.lang.ref.Reference}</code> class. An instance of one of
+these subclasses encapsulates a single reference to a particular object, called
+the <em>referent</em>. Every reference object provides methods for getting and
+clearing the reference. Aside from the clearing operation reference objects
+are otherwise immutable, so no <code>set</code> operation is provided. A
+program may further subclass these subclasses, adding whatever fields and
+methods are required for its purposes, or it may use these subclasses without
+change.
+
+
+<h3>Notification</h3>
+
+A program may request to be notified of changes in an object's reachability by
+<em>registering</em> an appropriate reference object with a <em>reference
+queue</em> at the time the reference object is created. Some time after the
+garbage collector determines that the reachability of the referent has changed
+to the value corresponding to the type of the reference, it will add the
+reference to the associated queue. At this point, the reference is considered
+to be <em>enqueued</em>. The program may remove references from a queue either
+by polling or by blocking until a reference becomes available. Reference
+queues are implemented by the <code>{@link java.lang.ref.ReferenceQueue}</code>
+class.
+
+<p> The relationship between a registered reference object and its queue is
+one-sided. That is, a queue does not keep track of the references that are
+registered with it. If a registered reference becomes unreachable itself, then
+it will never be enqueued. It is the responsibility of the program using
+reference objects to ensure that the objects remain reachable for as long as
+the program is interested in their referents.
+
+<p> While some programs will choose to dedicate a thread to removing reference
+objects from one or more queues and processing them, this is by no means
+necessary. A tactic that often works well is to examine a reference queue in
+the course of performing some other fairly-frequent action. For example, a
+hashtable that uses weak references to implement weak keys could poll its
+reference queue each time the table is accessed. This is how the <code>{@link
+java.util.WeakHashMap}</code> class works. Because the <code>{@link
+java.lang.ref.ReferenceQueue#poll ReferenceQueue.poll}</code> method simply
+checks an internal data structure, this check will add little overhead to the
+hashtable access methods.
+
+
+<h3>Automatically-cleared references</h3>
+
+Soft and weak references are automatically cleared by the collector before
+being added to the queues with which they are registered, if any. Therefore
+soft and weak references need not be registered with a queue in order to be
+useful, while phantom references do. An object that is reachable via phantom
+references will remain so until all such references are cleared or themselves
+become unreachable.
+
+
+<a name="reachability"></a>
+<h3>Reachability</h3>
+
+Going from strongest to weakest, the different levels of reachability reflect
+the life cycle of an object. They are operationally defined as follows:
+
+<ul>
+
+<li> An object is <em>strongly reachable</em> if it can be reached by some
+thread without traversing any reference objects. A newly-created object is
+strongly reachable by the thread that created it.
+
+<li> An object is <em>softly reachable</em> if it is not strongly reachable but
+can be reached by traversing a soft reference.
+
+<li> An object is <em>weakly reachable</em> if it is neither strongly nor
+softly reachable but can be reached by traversing a weak reference. When the
+weak references to a weakly-reachable object are cleared, the object becomes
+eligible for finalization.
+
+<li> An object is <em>phantom reachable</em> if it is neither strongly, softly,
+nor weakly reachable, it has been finalized, and some phantom reference refers
+to it.
+
+<li> Finally, an object is <em>unreachable</em>, and therefore eligible for
+reclamation, when it is not reachable in any of the above ways.
+
+</ul>
