Question

I am looking for an event or notification that enables me to react in my Eclipse-Plugin when methods of a (java)classes are changed (renamed or removed/added).
I am particularly interested in the IJavaElement representation of the method that is changed.

Does some kind of event exists that provides me with this kind of information?

Answer 1

this is my plugin.xml

<extension
     point="org.eclipse.ltk.core.refactoring.renameParticipants">
  <renameParticipant
        class="bookmark.renameparticipant.JavaElementRenameParticipant"
        id="bookmark-pp.bookmark.renameParticipant1"
        name="name">
     <enablement>
        <with
              variable="element">
           <or>
              <instanceof
                    value="org.eclipse.jdt.core.ICompilationUnit">
              </instanceof>
              <instanceof
                    value="org.eclipse.jdt.core.IType">
              </instanceof>
              <instanceof
                    value="org.eclipse.jdt.core.IMethod">
              </instanceof>
              <instanceof
                    value="org.eclipse.jdt.core.IField">
              </instanceof></or>
        </with>
     </enablement>
  </renameParticipant>

and my source of my rename participant:

I set a breakpoint in the init-method of the participant, but if I use CTRL+2+R in Eclipse not even the init is called:

@Override
    protected boolean initialize(Object element) {

        if (!(element instanceof IJavaElement)) {
            return false;
        }

        oldHandleId = ((IJavaElement) element).getHandleIdentifier();
        detectElementType((IJavaElement) element);

        newHandleId = generateNewHandleId(oldHandleId);

        if (!initSuccessful()) {
            return false;
        }

        return true;
    }
