    26 /**

    27  * Provides a collection of interfaces and classes that compose the Java Accessibility

    28  * Utilities.  The classes are used by Assistive Technologies, such as the screen

    29  * readers which are used by those who are blind, and help provide access to GUI

    30  * toolkits that implement the Java Accessibility API.  An overview of the important

    31  * classes follows.

    32  *

    33  * <p>The class {@code AccessibilityEventMonitor} implements a PropertyChange

    34  * listener on every UI object that implements interface {@code Accessible} in the Java

    35  * Virtual Machine.

    36  *

    37  * <p> The class {@code AWTEventMonitor} implements a suite of listeners that are

    38  * conditionally installed on every AWT component instance in the Java Virtual Machine.

    39  *

    40  * <p>The class {@code EventQueueMonitor} provides key core functionality for

    41  * Assistive Technologies (and other system-level technologies that need some of

    42  * the same things that Assistive Technology needs).

    43  *

    44  * <p>The class {@code GUIInitializedMulticaster} is used to maintain a list of

    45  * {@code GUIInitializedListener} classes which are used by the {@code EventQueueMonitor}

    46  * class to notify an interested party when the GUI subsystem has been initialized.

    47  * Note that this class is intended to be used primarily for internal support in

    48  * the {@code EventQueueMonitor} class, and is not intended to be used by classes

    49  * outside the Java Accessibility Utility package.

    50  *

    51  * <p>The class {@code SwingEventMonitor} extends {@code AWTEventMonitor} by adding

    52  * a suite of listeners conditionally installed on every Swing component instance

    53  * in the Java Virtual Machine.

    54  *

    55  * <p>The class {@code TopLevelWindowMulticaster} is used to maintain a list of

    56  * {@code TopLevelWindowListener} classes which are used by the {@code EventQueueMonitor}

    57  * class to notify an interested party when a top level window is created or destroyed

    58  * in the Java Virtual Machine  Note that this class is intended to be used primarily

    59  * for internal support in the {@code EventQueueMonitor} class, and is not intended

    60  * to be used by classes outside the Java Accessibility Utility package.

    61  *

    62  * <p>The class {@code Translator} provides a translation to interface {@code Accessible}

    63  * for objects that do not implement interface {@code Accessible}.

    64  *

    65  * @since JDK1.7
