WaitDispatchSupport	back to summary
public WaitDispatchSupport(EventDispatchThread dispatchThread, Conditional extCondition, EventFilter filter, long interval) Creates a `WaitDispatchSupport` instance to serve the given event dispatch thread. The `EventFilter` is set on the `dispatchThread` while waiting. The filter is removed on completion of the waiting process.

Method Detail

enter back to summary

enter	back to summary
public boolean enter() Implements java.awt.SecondaryLoop.enter. Doc from java.awt.SecondaryLoop.enter. Blocks the execution of the current thread and enters a new secondary event loop on the event dispatch thread. This method can be called by any thread including the event dispatch thread. This thread will be blocked until the `exit` method is called or the loop is terminated. A new secondary loop will be created on the event dispatch thread for dispatching events in either case. This method can only start one new event loop at a time per object. If a secondary event loop has already been started by this object and is currently still running, this method returns `false` to indicate that it was not successful in starting a new event loop. Otherwise, this method blocks the calling thread and later returns `true` when the new event loop is terminated. At such time, this object can again be used to start another new event loop.

exit back to summary

exit	back to summary
public boolean exit() Implements java.awt.SecondaryLoop.exit. Doc from java.awt.SecondaryLoop.exit. Unblocks the execution of the thread blocked by the `enter` method and exits the secondary loop. This method resumes the thread that called the `enter` method and exits the secondary loop that was created when the `enter` method was invoked. Note that if any other secondary loop is started while this loop is running, the blocked thread will not resume execution until the nested loop is terminated. If this secondary loop has not been started with the `enter` method, or this secondary loop has already finished with the `exit` method, this method returns `false`, otherwise `true` is returned.

public boolean exit()

This method resumes the thread that called the enter method and exits the secondary loop that was created when the enter method was invoked.

Note that if any other secondary loop is started while this loop is running, the blocked thread will not resume execution until the nested loop is terminated.

If this secondary loop has not been started with the enter method, or this secondary loop has already finished with the exit method, this method returns false, otherwise true is returned.
