Class AnnotationEditor.DelayedListener
java.lang.Object
|
+--gate.gui.AnnotationEditor.DelayedListener
- All Implemented Interfaces:
- AnnotationSetListener, DocumentListener, EventListener, Runnable
- Enclosing class:
- AnnotationEditor
- class AnnotationEditor.DelayedListener
- extends Object
- implements DocumentListener, AnnotationSetListener, Runnable
Used to process a bunch of events after they happened. E.g. when a
processing resource runs over a document it is likely to generate a set of
new annotations. We don't want the interface to be updated for each of
them but rather to be updated from time to time with a bunch of
annnotations at a time.
This listener runs in its own thread that mostly sleeps and only wakes up
when there are unprocessed events after a given time interval
(sleepInterval
) has passed from the last event occured. When the
thread wakes it will process all the pending events and
then will go back to sleep.
