[cfe-dev] better way to test for explicit C++ constructor?

[Peeter Joot]

Thanks Kim, that worked nicely:

         for ( CXXRecordDecl::ctor_iterator b = r->ctor_begin(), e =
r->ctor_end() ;
               b != e ; ++b )
         {
            if ( !b->isImplicitlyDefined() )
            {
               cout << r->getName().str() << " : CONSTRUCTOR" << endl ;

               break ;
            }
         }

and is much cleaner.

CXXRecordDecl has a ctor_begin/ctor_end pair, which return iterators
