Potentially useful JDT APIs

• for issue #28:

  • org.eclipse.jface.text.Position with IDocument.addPosition(Position)

  • or org.eclipse.jdt.core.dom.rewrite.ASTRewrite.track(ASTNode node)

• ITextEditor.getSelectionProvider().setSelection(ISelection)

  TextSelection selection = new TextSelection(position.getOffset(), position.getLength());
  ITextEditor editor = ...;
  editor.getSelectionProvider().setSelection(selection);

• org.eclipse.core.runtime.jobs.JobGroup, see bug 432049 for issue #107

• org.eclipse.jface.text.IDocumentExtension4.startRewriteSession(DocumentRewriteSessionType)

• DocumentUndoManager.beginCompoundChange() and IDocumentUndoManager.endCompoundChange():

  IDocumentUndoManager manager = DocumentUndoManagerRegistry.getDocumentUndoManager(document);
  manager.beginCompoundChange();
  edit.apply(document);
  manager.endCompoundChange();

• Insert empty line, or insert comments from the ASTRewriter (see 1 and 2):

  Statement commentPlaceHolder = (Statement)
      rewriter.createStringPlaceholder("//mycomment", ASTNode.EMPTY_STATEMENT);
  listRewrite.insertFirst(commentPlaceHolder, null);
  //notice here, we just create a string placeholder, and string is simply empty
  Statement emptyLinePlaceHolder = (Statement)
      rewriter.createStringPlaceholder("", ASTNode.EMPTY_STATEMENT);
  listRewrite.insertFirst(emptyLinePlaceHolder, null)
