c++ - How to get the base class from this example with Clang ? -

here basic sample of code, , have :

class b{     // implementation of class b }; class d : public b{     // implementation of class d }; int main(){     try{         // code try statement     }     catch(d & d){         // handler d      }      catch(b & b){         // handler b      }      return 0;  }  

currently able cxxrecorddecl of class b , class d, in handlers (i can them getcaughttype method in cxxcatchstmt class).

what able access cxxrecorddecl of class b class d, since have class d : public b.

i have tried following methods available in class cxxrecorddecl on cxxrecorddecl of class d:

• getcanonicaldecl() : returns class d
• getinstantiatedfrommemberclass() : returns nullptr
• getdefinition() : returns class d

i'm out of ideas right now. have idea ?

here implementation of answer given joachim pileborg in comments.

bool visitcxxtrystmt(cxxtrystmt * trystmt){     int nbcatch = trystmt->getnumhandlers();      for(int = 0 ; < nbcatch ; i++){         if(trystmt->gethandler(i)->getcaughttype().gettypeptr()->getpointeecxxrecorddecl() == nullptr){             cout << "the caught type not class" << endl;          }         else{             cout << "class caught : " << trystmt->gethandler(i)->getcaughttype().gettypeptr()->getpointeecxxrecorddecl()->getnameasstring() << endl;         }          if(trystmt->gethandler(i)->getcaughttype().gettypeptr()->getpointeecxxrecorddecl()->bases_begin() == nullptr){             cout << "this class base class" << endl;          }         else{             cout << "base class caught : " << trystmt->gethandler(i)->getcaughttype().gettypeptr()->getpointeecxxrecorddecl()->bases_begin()->gettype().getasstring() << endl;         }          cout << "\n \n end of loop \n \n" << endl;      }      return true;  } 

yields following output example given in question :

class caught : d

base class caught : class b

end of loop

class caught : b

this class base class

end of loop
