Of course you can use 'HandleTopLevelDecl'. Just check if the current
declaration happens to be a C++ class declaration and if so iterate
through its methods

>       const CXXRecordDecl *CRD = cast<CXXRecordDecl>(D);

> 	  cMeth = CRD->method_begin(),
> 	  endMeth = CRD->method_end();
> 	  cMeth != endMeth; ++cMeth) {
> 
> 		CXXMethodDecl* mD = *cMeth;
