How to analyze fine-grained source code change with AST [message #204443]

Hi,

I want to observe and possibly respond to fine-grained source code changes
in my plug-in.
I plan to use the IJavaElementDeltas for structural changes but I'm also
interested in more details i.e. changes in the body of a method.

To solve this, my impression is that to use the AST is the way to go.

Please give me feedback if there is a better way but I want to compare the
altered/new code with the previous/old code (compare AST models of the
ICompilationUnits using the ASTMatcher) to get the changes.

Couple of questions: is the comparing of ICompilationUnits available
already?

Do I have to store a "old" copy of the source myself or can I get hold of it
somehow (how does redo know what the code was..)?

Thanks in advance,

Otto
