Is there any good documentation on implementing new refactorings in Eclipse? Specifically, I'd like to access the AST for a Java class, make some non-trivial changes, and save the result back to the source file.
So far, the only documentation I've found is (1) the source code for the existing refactorings and (2) a few articles on the LTK and Java AST:
Are there any other articles or tutorials that I should read?

Refactoring using Eclipse Right clicking on a Java element in the Package Explorer view and selecting Refactor menu item.

Compositional Refactoring This Eclipse bundle provides new Quick Assist actions to support refactorings in a compositional paradigm. In the compositional paradigm, the tool automates small, predictable steps of a refactorin...
Eclipse makes this absurdly easy to do. Right-click on almost anything and choose Refactor > Rename. Type in a new name for whatever it is, and make sure that the Update References checkbox is checked. This will ensure that all references in all of your code will be updated.
I found the eclipse.org article the most helpful to get me started. To be honest you're probably best off debugging some of the Eclipse refactorings to get a real feel for how they work.
A good place to get started debugging the code is to set breakpoints on org.eclipse.jdt.core.dom.rewrite.ASTRewrite, particularly the rewriteAST() method, then trigger some refactorings.
Here are a few you might find useful. Are you looking for anything in particular or a general sense of how to process the AST?

You can take a look at Lombok Project. It seems they have Eclipse plugin.
It does some AST manipulations - e.q. getters/setters. Could be helpful for you too.
