| Inheritance |

An instance of this object is returned when you add a custom event handler using pdg.Node.addEventHandler() or pdg.GraphContext.addEventHandler(). If you want to remove the handler later, you can this object to pdg.Node.removeEventHandler() or pdg.GraphContext.removeEventHandler(). Alternatively, you can remove the handler from any event emitter its attached to by calling pdg.EventHandler.removeAllEventEmitters.
