Class AssociationEvent

java.lang.Object

      org.netbeans.api.mdr.events.MDRChangeEvent
          org.netbeans.api.mdr.events.AssociationEvent

All Implemented Interfaces:: Serializable

public class AssociationEvent
extends MDRChangeEvent
extends MDRChangeEvent

MDR Event used for representing association-related events. Any association event is described the way that there is one association end taken as "fixed". This means that the change will be described from the perspective of this association end. For changes to the association caused by modifying a reference or live collection returned from a getter for an association end this behavior is very intuitive - the fixed association end will be the exposed end of the reference (or the fixed element will be the element provided to getter for association end). For direct association proxy operations (i.e. remove or add), the event object looks as follows:

remove - the fixed element is any of the two linked elements, old element represents the element on the other side of the link, new element is null
add - the fixed element is any of the two linked elements, old element is null, the element on the other side of the link is represented as the new element.
