Package ipsk.awt

Class AWTEventTransferAgent<L extends java.util.EventListener,E extends java.util.EventObject>

java.lang.Object

ipsk.awt.AWTEventTransferAgent<L,E>

Direct Known Subclasses:

ProgressWorker.ProgressEventTransferAgent, PropertyChangeAWTEventTransferAgent, UpdateAWTEventTransferAgent, UploadCache.EventTransformer

public abstract class AWTEventTransferAgent<L extends java.util.EventListener,E extends java.util.EventObject>
extends java.lang.Object

Agent transfers events from arbitrary threads to the AWT-Event-Thread. Swing components are not thread save. With this class events of concurrent running threads can be transferred to the AWT-Event-Thread. Actions triggered by these events can call Swing methods in a safety way without placing the method calls in an extra Runnable and push it to the AWT-Event-Thread queue.
