    the only instance of this class
  - 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.
