Constructor Detail

JavaElementDelta

public JavaElementDelta(IJavaElement element)

Creates the root delta. To create the nested delta hierarchies use the following convenience methods. The root delta can be created at any level (for example: project, package root, package fragment...).

• added(IJavaElement)
• changed(IJavaElement)
• moved(IJavaElement, IJavaElement)
• removed(IJavaElement)
• renamed(IJavaElement, IJavaElement)

Method Detail

added

public void added(IJavaElement element)

Creates the nested deltas resulting from an add operation. Convenience method for creating add deltas. The constructor should be used to create the root delta and then an add operation should call this method.

added

public void added(IJavaElement element,
                  int flags)

changed

public JavaElementDelta changed(IJavaElement element,
                                int changeFlag)

Creates the nested deltas resulting from a change operation. Convenience method for creating change deltas. The constructor should be used to create the root delta and then a change operation should call this method.

changedAST

public void changedAST(CompilationUnit changedAST)

contentChanged

public void contentChanged()

Mark this delta as a content changed delta.

closed

public void closed(IJavaElement element)

Creates the nested deltas for a closed element.

fineGrained

public void fineGrained()

Mark this delta as a fine-grained delta.

getAddedChildren

public IJavaElementDelta[] getAddedChildren()

Description copied from interface: IJavaElementDelta

Returns deltas for the children that have been added.

Specified by:

getAddedChildren in interface IJavaElementDelta

Returns:

deltas for the children that have been added

See Also:

IJavaElementDelta

getAffectedChildren

public IJavaElementDelta[] getAffectedChildren()

Description copied from interface: IJavaElementDelta

Returns deltas for the affected (added, removed, or changed) children.

Specified by:

getAffectedChildren in interface IJavaElementDelta

Returns:

deltas for the affected (added, removed, or changed) children

See Also:

IJavaElementDelta

getCompilationUnitAST

public CompilationUnit getCompilationUnitAST()

Description copied from interface: IJavaElementDelta

Returns the compilation unit AST created by the last reconcile operation on this delta's element. This returns a non-null value if and only if:

• the last reconcile operation on this working copy requested an AST
• this delta's element is an ICompilationUnit in working copy mode
• the delta comes from a ElementChangedEvent.POST_RECONCILE event

Specified by:

getCompilationUnitAST in interface IJavaElementDelta

Returns:

the AST created during the last reconcile operation

See Also:

ICompilationUnit.reconcile(int, boolean, WorkingCopyOwner, org.eclipse.core.runtime.IProgressMonitor), IJavaElementDelta.F_AST_AFFECTED

getAnnotationDeltas

public IJavaElementDelta[] getAnnotationDeltas()

Description copied from interface: IJavaElementDelta

Returns deltas for affected annotations (added, removed, or changed). Returns an empty array if no annotations was affected, or if this delta's element is not an IAnnotatable.

Specified by:

getAnnotationDeltas in interface IJavaElementDelta

Returns:

deltas for affected annotations (added, removed, or changed)

getChangedChildren

public IJavaElementDelta[] getChangedChildren()

Description copied from interface: IJavaElementDelta

Returns deltas for the children which have changed.

Specified by:

getChangedChildren in interface IJavaElementDelta

Returns:

deltas for the children which have changed

See Also:

IJavaElementDelta

getElement

public IJavaElement getElement()

Description copied from interface: IJavaElementDelta

Returns the element that this delta describes a change to.

Specified by:

getElement in interface IJavaElementDelta

Returns:

the element that this delta describes a change to

See Also:

IJavaElementDelta

getMovedFromElement

public IJavaElement getMovedFromElement()

Description copied from interface: IJavaElementDelta

Returns an element describing this element before it was moved to its current location, or null if the IJavaElementDelta.F_MOVED_FROM change flag is not set.

Specified by:

getMovedFromElement in interface IJavaElementDelta

Returns:

an element describing this element before it was moved to its current location, or null if the IJavaElementDelta.F_MOVED_FROM change flag is not set

See Also:

IJavaElementDelta

getMovedToElement

public IJavaElement getMovedToElement()

Description copied from interface: IJavaElementDelta

Returns an element describing this element in its new location, or null if the IJavaElementDelta.F_MOVED_TO change flag is not set.

Specified by:

getMovedToElement in interface IJavaElementDelta

Returns:

an element describing this element in its new location, or null if the IJavaElementDelta.F_MOVED_TO change flag is not set

See Also:

IJavaElementDelta

Return the collection of resource deltas. Return null if none.

Specified by:

getResourceDeltas in interface IJavaElementDelta

Returns:

the underlying resource deltas, or null if none

movedFrom

public void movedFrom(IJavaElement movedFromElement,
                      IJavaElement movedToElement)

Creates the nested deltas resulting from an move operation. Convenience method for creating the "move from" delta. The constructor should be used to create the root delta and then the move operation should call this method.

movedTo

public void movedTo(IJavaElement movedToElement,
                    IJavaElement movedFromElement)
