Class UserEmailEntityListener

java.lang.Object

ch.tocco.nice2.usermanager.impl.UserEmailEntityListener

All Implemented Interfaces:

EntityFacadeListener, CommitListener, EventListener

public class UserEmailEntityListener
extends Object
implements EntityFacadeListener, CommitListener

Sends an email to the "old" email address if the email field of an User has changed. This listener implements the EntityFacadeListener and CommitListener because it needs to know the old value of the field but must not send the email until the new value was saved. It is not possible to get the old value of the field within an CommitListener why it is necessary to combine this two interfaces. In the hivemodule.xml this listener is registered as EntityFacadeListener. If the email field on an user entity was changed the user plus the old value of the field are set as an attribute to the context of the user entity. Also this listener then will be added as CommitListener to the same context so the email can be send after the value was saved within the afterCommit method where this listener then also will be removed again from the context.
