Call rename element [message #1727059]

Hi,

I wish to rename programmatically an element in my model. For now I use a code similar to the one below.

The good thing is that it works, i.e. it renames the actor.

BUT unfortunately, all cross-references pointing to this element are NOT renamed.

- Maybe a first solution could be to perform a call to the "Rename Element" feature on my given EObject. But I have no clue on how to do that ?

- or any other solution that would notify the model that the EObject has been modified and forces the update of all its cross-references.

Any idea how I can call it directly do that ?

best regards,
Benoît

here is my current code:

IXtextDocument myDocument = XtextUtils.getXTextDocumentFromEObject(act);
myDocument.modify(new IUnitOfWork.Void<XtextResource>() {
@Override
public void process(XtextResource xtextResource) throws Exception {
PackageDeclaration pkg = (PackageDeclaration) xtextResource.getContents().get(0);
for (Actor actTmp: pkg.getEnvironmentM().getActors()) {
actTmp.setName(newName);
}}});

This may look bulky, but it should do what you expected. Of course you may use real monitors or provide better user feedback on errors.

@Inject private Provider<RenameElementProcessor> processorProvider;
...
RenameElementProcessor processor = processorProvider.get();
processor.initialize(new IRenameElementContext.Impl(targetElementURI, RefactoringPackage.Literals.ELEMENT);
processor.setNewName(newName);
RefactoringStatus initialStatus = processor.checkInitialConditions(new NullProgressMonitor());
if(initialStatus.isOK()) {
  RefactoringStatus finalStatus = processor.checkFinalConditions(new NullProgressMonitor(), null);
  if(finalStatus.isOK()) {
    Change change = processor.createChange(new NullProgressMonitor());
    new WorkspaceModifyOperation() {
      @Override
      protected void execute(IProgressMonitor monitor) throws CoreException, InvocationTargetException, InterruptedException {
        change.perform(monitor);
      }
    }.run(null);
  } 
}
