Class UpdateConnectoidsOnVertexRemovalHandler

  • All Implemented Interfaces:
    EventListener, EventListener, DirectedGraphModifierListener, GraphModifierListener
    public class UpdateConnectoidsOnVertexRemovalHandler
extends Object
implements DirectedGraphModifierListener
    A listener designed to deal with the situation that sub graphs are removed from the network which leaves connectoids in the zoning that reference these sub graph elements invalid. This listener should be used to register on the DirectedGraphModifier before any call to GraphModifier.removeSubGraph in which case callbacks are triggered which allow this instance to update the connectoids, i.e., remove any affected connectoids that are no longer valid.

      • getKnownSupportedEventTypes

        public EventType[] getKnownSupportedEventTypes()
        Collect explicitly supported event types that are known. When not defined the user has to explicitly provide them upon registering the listener on an event producer, otherwise they can be extracted from here
        Specified by:
        getKnownSupportedEventTypes in interface EventListener
        Returns:
        the supported event types
