ch.tocco.nice2.persist.core.api.util.CollectingEntityListener

ch.tocco.nice2.dms.impl.entitylistener.SetChildrenFlagListener

All Implemented Interfaces:

ContextListener, EntityFacadeListener, CommitListener, EventListener

public class SetChildrenFlagListener
extends CollectingEntityListener

Sets a boolean flag "has_children" on container nodes. This results in better performance for leafs since a resolve for children is not necessary if we know that it does not have any children anyways.
