Class ElementChangedEvent


java.lang.Object
  

java.util.EventObject
      
org.eclipse.jdt.core.ElementChangedEvent

All Implemented Interfaces:: Serializable

public class ElementChangedEvent
extends EventObject
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.

Field Summary

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

Field Detail

POST_CHANGE

public static final int POST_CHANGE

Since:: 2.0
See Also:: IJavaElementDelta, IResourceChangeEvent, getDelta(), Constant Field Values

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).

Since:: 2.0

POST_RECONCILE

public static final int POST_RECONCILE

Since:: 2.0

public ElementChangedEvent(
IJavaElementDelta delta,
