[news.eclipse.tools] How to get AST for an IMethod (again)

[Simon Giesecke <simon.giesecke@xxxxxxx>]

Hi,

I know that the question has already been posted here, but I need some
clarification.

It is clear to me that I need to parse the method's compilation unit by

AST.parseCompilationUnit(method.getCompilationUnit())

Then, of course, I have the AST for the whole compilation unit, but how do
I easily find the subtree refering to my method?

At the moment I use an ASTVisitor to search the tree and compare the
IMethod.getSourceRange with MethodDeclaration.getStartPosition/getLength

First, this doesn't look very efficient to me, but what is more severe, it
doesn't work in at least one case: If there is a Non-JavaDoc-comment
preceding the method declaration, IMethod.getSourceRange contains the
comment and MethodDeclaration.getStartPosition/getLength does NOT.

If this is the only deviance between the two notions of source range, I
could of cause catch this case, but I have not found any specification of
what the ISourceRange of an ISourceReference implementor exactly is.

Kind regards,
Simon
