Class ElementChangedEvent

  • All Implemented Interfaces:
    Serializable

    public class ElementChangedEvent
    extends EventObject
    An element changed event describes a change to the structure or contents of a tree of Java elements. The changes to the elements are described by the associated delta object carried by this event.

    This class is not intended to be instantiated or subclassed by clients. Instances of this class are automatically created by the Java model.

      Fields 
      Modifier and Type Field Description
      static int POST_CHANGE
      Event type constant (bit mask) indicating an after-the-fact report of creations, deletions, and modifications to one or more Java element(s) expressed as a hierarchical java element delta as returned by getDelta().
      static int POST_RECONCILE
      Event type constant (bit mask) indicating an after-the-fact report of creations, deletions, and modifications to one or more Java element(s) expressed as a hierarchical java element delta as returned by getDelta.
      static int PRE_AUTO_BUILD
      Deprecated.
      - no longer used, such deltas are now notified during POST_CHANGE

      • POST_CHANGE

        public static final int POST_CHANGE
        Event type constant (bit mask) indicating an after-the-fact report of creations, deletions, and modifications to one or more Java element(s) expressed as a hierarchical java element delta as returned by getDelta(). Note: this notification occurs during the corresponding POST_CHANGE resource change notification, and contains a full delta accounting for any JavaModel operation and/or resource change.

        2.0

      • PRE_AUTO_BUILD

        public static final int PRE_AUTO_BUILD
        Deprecated.
        - no longer used, such deltas are now notified during POST_CHANGE
        Event type constant (bit mask) indicating an after-the-fact report of creations, deletions, and modifications to one or more Java element(s) expressed as a hierarchical java element delta as returned by getDelta. Note: this notification occurs during the corresponding PRE_AUTO_BUILD resource change notification. The delta, which is notified here, only contains information relative to the previous JavaModel operations (in other words, it ignores the possible resources which have changed outside Java operations). In particular, it is possible that the JavaModel be inconsistent with respect to resources, which got modified outside JavaModel operations (it will only be fully consistent once the POST_CHANGE notification has occurred).

      • POST_RECONCILE

        public static final int POST_RECONCILE
        Event type constant (bit mask) indicating an after-the-fact report of creations, deletions, and modifications to one or more Java element(s) expressed as a hierarchical java element delta as returned by getDelta. Note: this notification occurs as a result of a working copy reconcile operation.
