How do I get an IResource from an IEditorActionDelegate

Question

I wrote an IEditorActionDelegate to fire from a context menu on a CompilationUnitEditor. From there I want to create a marker at the start line of the selected text. I have an ITextSelection, and an IEditorPart object. How can I get an IResource from those so that I can call resource.createMarker()?

Thanks

May be you can look at how Eclipse does something similar in its org.eclipse.jdt.internal.ui.javaeditor.EditorUtility class.

You can see (line 222 and following) it:

final IEditorInput  input= editor.getEditorInput();
marker= ((IFileEditorInput)input).getFile().createMarker(IMarker.TEXT);
marker.setAttribute(IMarker.CHAR_START, offset);
marker.setAttribute(IMarker.CHAR_END, offset + length);

With offset and length something you should be able to infer from your TextSelection.
