      • 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.
