Method Details

public final void markAsProcessed()

Signals that the processing of this event is finished. Do not touch this method as it is designed for invocation by org.luwrain.core.Environment class only which controls the event loop. Once this method is called, all threads freezed on waitForBeProcessed() method continue the execution.

public final void waitForBeProcessed()
                              throws InterruptedException

This method may not be used in the same thread as the main thread of the core (there are no any corresponding checks). The improper use of this method will hang the system infinitely.

InterruptedException - if the thread should terminate
