JRE 8 rt.jar - java.* Package Source Code

JRE 8 rt.jar is the JAR file for JRE 8 RT (Runtime) libraries. JRE (Java Runtime) 8 is the runtime environment included in JDK 8. JRE 8 rt.jar libraries are divided into 6 packages:

com.* - Internal Oracle and Sun Microsystems libraries
java.* - Standard Java API libraries.
javax.* - Extended Java API libraries.
jdk.* -  JDK supporting libraries.
org.* - Third party libraries.
sun.* - Old libraries developed by Sun Microsystems.

/**
 * This abstract subclass of <code>DragGestureRecognizer</code>
 * defines a <code>DragGestureRecognizer</code>
 * for mouse-based gestures.
 *
 * Each platform implements its own concrete subclass of this class,
 * available via the Toolkit.createDragGestureRecognizer() method,
 * to encapsulate
 * the recognition of the platform dependent mouse gesture(s) that initiate
 * a Drag and Drop operation.
 * <p>
 * Mouse drag gesture recognizers should honor the
 * drag gesture motion threshold, available through
 * {@link DragSource#getDragThreshold}.
 * A drag gesture should be recognized only when the distance
 * in either the horizontal or vertical direction between
 * the location of the latest mouse dragged event and the
 * location of the corresponding mouse button pressed event
 * is greater than the drag gesture motion threshold.
 * <p>
 * Drag gesture recognizers created with
 * {@link DragSource#createDefaultDragGestureRecognizer}
 * follow this convention.
