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 66 */ 67 package com.sun.java.accessibility.util;
