[cfe-dev] Querying C++ function declarations

[Ted Kremenek]

Hi Oksana,

If the FunctionDecl represents a C++ method, it actually will be an instance of CXXMethodDecl.  Try doing:

  FunctionDecl *FD = ...
  ...
  if (CXXMethodDecl *MD = dyn_cast<CXXMethodDecl>(FD)) {


  }

Once you have a CXXMethodDecl*, you should be able to directly do most of the things you are asking for, including finding the enclosing class (via getParent()).  I don't know off the top of my head, however, how to get the access control (as it was declared) for the method.
