runBatch

public static void runBatch(java.lang.Runnable runnable)

Executes a method inside a beginBatch() - endBatch() pair. See beginBatch() for more information. It's safe to call other batch methods from inside Runnable.run().

Parameters:

runnable - the runnable to invoke

beginBatch

public void beginBatch()

Begins a batch operation. This stores and merges all change notifications occuring in all property maps until endBatch() is called. Each call to this method MUST be followed by a call to endBatch(). This method can be called an unlimited number of times without calling endBatch() in between, but each call must have a corresponding call to endBatch(). Only when exiting from the outermost endBatch() the changes be propagated to the listeners.

endBatch

public void endBatch()

Ends a batch operation. See beginBatch() for more information.
