extension points in org.eclipse.ltk.core.refactoring [message #325846]

I need help understanding the refactoring API. I am concerned with
renaming, moving, deleting, and copying certain files in the navigator. I'm
not sure if I should be using the extension points in
org.eclipse.ltk.core.refactoring. When the user clicks one of our files in
the navigator, I want that file, and others, to have the operation performed
on them. Should I change the refactoring of rename, etc, or instead use
IResourceChangeListeners?

Is this type of refactoring documented or is the documentation in the code?

You would use participants to update other files when you see
move/delete/rename. There is an article available at:

What is the extension point org.eclipse.ltk.core.refactoring used for then?
I don't see that in the article.

It is mentioned (just in passing :-) in the "Refactoring Participants
(as of Eclipse 3.2M2)" box. Those extensions are how a plugin would
contribute new refactorings (and participants to existing refactorings).

There should be some information in the extension point description.
And as they mention, if you import the PDE plugins as source you should
see examples of the participants being used (so when a Java class is
renamed, the plugin.xml files can be updated to the new class name, etc).

i.e. so if you wanted to add a new MoveMyModel refactoring, you would
use org.eclipse.ltk.core.refactoring.refactoringContributions and if you
wanted to update some of your files on a Java Move refactoring you would
use org.eclipse.ltk.core.refactoring.moveParticipants.

As of 3.4 the navigator move, delete, and rename menu actions default to
using LTK refactorings. That means that adding a participant would
allow you to participate in those operations.
