MapTriggerListener is a special purpose MapListener implementation that is used to register a MapTrigger on a corresponding ObservableMap.

Note: Currently, the MapTriggerListener can only be registered with partitioned caches and only "globally" (without specifying any filter or key), using the ObservableMap.addMapListener(MapListener) method.
