Bug 327753

Description Christophe Le Camus 2010-10-14 06:34:20 EDT

Build Identifier: Eclipse SDK  Version: 3.6.0 I20100608-0911

This question is relative to the CDT event detection.
The interface ICElementDelta publishes the following methods :
 ICElementDelta[] 	getAddedChildren()
          Returns deltas for the children that have been added.
 ICElementDelta[] 	getAffectedChildren()
          Returns deltas for the affected (added, removed, or changed)
children.
 ICElementDelta[] 	getChangedChildren()
          Returns deltas for the children which have changed.

However the content of the getChangedChildren() is always empty even if some
nodes are affected by a modification.
A modification is materialised as a creation event + a deletion event but
without any link between them.
or in another words :
To replace this modification information 2 events are published :
-one concerning the deletion of the old node (because name change, the old
node is considered deleted)
-one concerning the addition of a new  node (because the modification of the
name induces the creation of a different node from the old one).

I'd want to know if Eclipse has planned to enhance the management of
ICElementDelta with the implementation of the ICElementDelta[]
getChangedChildren() method ? If positive, when is it planned ?  Else, do
does exist a solution to be sure that the new node is the old one with little
modification ?

Thanks


Reproducible: Always

Steps to Reproduce:
// ICElementDelta delta;

        IWorkingCopy workingUnit = (IWorkingCopy) delta.getElement();
        ITranslationUnit originalUnit = workingUnit.getOriginalElement();
// always OK
        ICElementDelta[] children = delta.getAffectedChildren();
        ICElementDelta[] addedChildren = delta.getAddedChildren();
        ICElementDelta[] removedChildren = delta.getRemovedChildren();
// always empty
        ICElementDelta[] removedChildren = delta.getChnagedChildren();
