[cfe-dev] Possibility to expose Deltas from the clang::RewriteBuffer?

[Won Tae Joo via cfe-dev]

Hi,

I am using clang libtooling to do a source to source transformation for C++.

I find the rewriting functionality quite useful, but I would also like
implement (in my tools) to report the points of the transformed source code
(e.g. The statement i++; in (5:1-5); has been transformed into i = i +
1;(5:1-10) . I believe this can happen via clang::Rewriter::Deltas(which
the type is clang::DeltaTree), but unfortunately this member is private.
Would there be any possibility to expose this member via 'const Deltatree
&' or would there be other options to be doing the things that I want?
