All Implemented Interfaces:

HGEvent

public class HGAtomRemoveRequestEvent
extends HGAtomEvent

A HGAtomRemoveRequestEvent is triggered when an attempt is made to remove an from HyperGraph, but before the removal process proceeds. This event gives a chance to an application to cancel the removal of an atom. A listener to this event may return the HGListener.Result.cancel code which will prevent the removal from happening. On the other hand, if an application needs to perform some action as a result to an already completed removal, the application should then listen to the HGAtomRemovedEvent.
