void |
invoke(boolean wait,
Runnable task)
Shall start the thread if not running. Append task to the EDT task queue. Wait until execution is finished if wait == true .Can be issued from within EDT, ie from within an enqueued task. |
void |
invokeStop(Runnable task)
Append the final task to the EDT task queue, signals EDT to stop and wait until stopped. Due to the nature of this method: All previous queued tasks will be finished. No new tasks are allowed, an Exception is thrown. Can be issued from within EDT, ie from within an enqueued task. EDTUtil.reset() may follow immediately, ie creating a new EDT
|
boolean |
isCurrentThreadEDT()
Returns true if the current thread is the event dispatch thread (EDT). |
boolean |
isCurrentThreadEDTorNEDT()
Returns true if either EDTUtil.isCurrentThreadEDT() or EDTUtil.isCurrentThreadNEDT() is true ,
otherwise false . |
boolean |
isCurrentThreadNEDT()
Returns true if the current thread is the internal NEWT event dequeue thread (NEDT). |
boolean |
isRunning()
|
void |
reset()
Create a new EDT. |
void |
setPollPeriod(long ms)
|
void |
waitUntilIdle()
Wait until the EDT task queue is empty. The last task may still be in execution when this method returns. |
void |
waitUntilStopped()
Wait until EDT task is stopped. No stop action is performed, EDTUtil.invokeStop(java.lang.Runnable) should be used before. |

public boolean isCurrentThreadEDT()
EDTUtil
The EDT is the platform specific thread dispatching toolkit-events
and executing toolkit-tasks enqueued via EDTUtil.invoke(boolean, Runnable)
.
Usually it is the same thread as used to dequeue informal NEWTEvent
s (NEDT), see EDTUtil.isCurrentThreadNEDT()
,
however, this may differ, e.g. SWT and AWT implementation.
isCurrentThreadEDT
in interface EDTUtil
public final boolean isCurrentThreadNEDT()
EDTUtil
The NEDT is the NEWT thread used to dequeue informal NEWTEvent
s enqueued internally
via DisplayImpl.enqueueEvent(boolean, NEWTEvent)
.
Usually it is the same thread as the EDT, see EDTUtil.isCurrentThreadEDT()
,
however, this may differ, e.g. SWT and AWT implementation.
