org.hypergraphdb.event.HGAtomProposeEvent

All Implemented Interfaces:

HGEvent

public class HGAtomProposeEvent
extends HGEventBase

Event triggered when a new atom is about to be added to the graph. Listeners may perform some other operation before the atom is added or may throw an exception to prevent the atom from being added. Returning HGListener.Result.cancel from the listener will also stop the atom addition, but without communicating further information upstream to the application.
