public class MapEventTransformerFilter<T> extends ExternalizableHelper implements Filter<T>, MapEventTransformer, ExternalizableLite, PortableObject
MapEventTransformerFilter is a generic multiplexing wrapper that combines two implementations: a Filter (most commonly aMapEventFilter
) and a MapEventTransformer and is used to register event listeners that allow to change the content of a MapEvent.- Since:
