Examples of IJavaElementDelta

org.aspectj.org.eclipse.jdt.core.IJavaElementDelta
A Java element delta describes changes in Java element between two discrete points in time. Given a delta, clients can access the element that has changed, and any children that have changed.
Deltas have a different status depending on the kind of change they represent. The list below summarizes each status (as returned by {@link #getKind}) and its meaning (see individual constants for a more detailled description):
- {@link #ADDED} - The element described by the delta has been added.
- {@link #REMOVED} - The element described by the delta has been removed.
- {@link #CHANGED} - The element described by the delta has been changed in some way. Specification of the type of change is provided by {@link #getFlags} which returns the following values:
  - {@link #F_ADDED_TO_CLASSPATH} - A classpath entry corresponding to the elementhas been added to the project's classpath. This flag is only valid if the element is an {@link IPackageFragmentRoot}.
  - {@link #F_ARCHIVE_CONTENT_CHANGED} - The contents of an archivehas changed in some way. This flag is only valid if the element is an {@link IPackageFragmentRoot}which is an archive.
  - {@link #F_CHILDREN} - A child of the element has changed in some way. This flagis only valid if the element is an {@link IParent}.
  - {@link #F_CLASSPATH_REORDER} - A classpath entry corresponding to the elementhas changed position in the project's classpath. This flag is only valid if the element is an {@link IPackageFragmentRoot}.
  - {@link #F_CLOSED} - The underlying {@link org.eclipse.core.resources.IProject}has been closed. This flag is only valid if the element is an {@link IJavaProject}.
  - {@link #F_CONTENT} - The contents of the element have been altered. This flagis only valid for elements which correspond to files.
  - {@link #F_FINE_GRAINED} - The delta is a fine-grained delta, that is, an analysis downto the members level was done to determine if there were structural changes to members of the element.
  - {@link #F_MODIFIERS} - The modifiers on the element have changed in some way. This flag is only valid if the element is an {@link IMember}.
  - {@link #F_OPENED} - The underlying {@link org.eclipse.core.resources.IProject}has been opened. This flag is only valid if the element is an {@link IJavaProject}.
  - {@link #F_REMOVED_FROM_CLASSPATH} - A classpath entry corresponding to the element has been removed from the project's classpath. This flag is only valid if the element is an {@link IPackageFragmentRoot}.
  - {@link #F_SOURCEATTACHED} - The source attachment path or the source attachment root pathof a classpath entry corresponding to the element was added. This flag is only valid if the element is an {@link IPackageFragmentRoot}.
  - {@link #F_SOURCEDETACHED} - The source attachment path or the source attachment root pathof a classpath entry corresponding to the element was removed. This flag is only valid if the element is an {@link IPackageFragmentRoot}.
  - {@link #F_SUPER_TYPES} - One of the supertypes of an {@link IType} has changed
Move operations are indicated by other change flags, layered on top of the change flags described above. If element A is moved to become B, the delta for the change in A will have status {@link #REMOVED}, with change flag {@link #F_MOVED_TO}. In this case, {@link #getMovedToElement} on delta A will return the handle for B.The delta for B will have status {@link #ADDED}, with change flag {@link #F_MOVED_FROM}, and {@link #getMovedFromElement} on deltaB will return the handle for A. (Note, the handle to A in this case represents an element that no longer exists).

Note that the move change flags only describe the changes to a single element, they do not imply anything about the parent or children of the element.

The {@link #F_ADDED_TO_CLASSPATH}, {@link #F_REMOVED_FROM_CLASSPATH} and{@link #F_CLASSPATH_REORDER} flags are triggered by changes to a project's classpath. They do not mean thatthe underlying resource was added, removed or changed. For example, if a project P already contains a folder src, then adding a classpath entry with the 'P/src' path to the project's classpath will result in an {@link IJavaElementDelta} with the {@link #F_ADDED_TO_CLASSPATH} flag for the {@link IPackageFragmentRoot} P/src.On the contrary, if a resource is physically added, removed or changed and this resource corresponds to a classpath entry of the project, then an {@link IJavaElementDelta} with the {@link #ADDED}, {@link #REMOVED}, or {@link #CHANGED} kind will be fired.

Note that when a source attachment path or a source attachment root path is changed, then the flags of the delta contain both {@link #F_SOURCEATTACHED} and {@link #F_SOURCEDETACHED}.

No assumptions should be made on whether the java element delta tree is rooted at the {@link IJavaModel}level or not.

{@link IJavaElementDelta} object are not valid outside the dynamic scopeof the notification.

This interface is not intended to be implemented by clients.
