How to get class objects stored in a list in C++? -

i've defined own class , stored objects of them in std:list. want pick elements, went wrong - hope not complicated read:

std::map < long, firstclass*> firstclassmap; std::map < long, firstclass* >::iterator it; it=this->firstclassmap.begin()  //initialization of firstclassmap somewhere else , shouldn't matter.  list<secondclass*>::iterator listitem; list<secondclass*> deplist = it->second->getsecondclasslist();  for(listitem = deplist.begin(); listitem != deplist.end(); ++listitem) {     /* -- error in line -- */     firstclass* theobject = listitem->getthelistobject();     std::cout << theobject->name(); } 

then there function:

secondclass::getthelistobject() {     return this->theobject; //returns firstclass object }  firstclass::name() {     return this->name //returns string } 

here error

method 'getthelistobject' not resolved

and

error:element request »getthelistobject« in »* listitem.std::_list_iterator<_tp>::operator->()«, pointer type »secondclass*« (maybe »->« meant)

(i'm sorry, can't give correct error message. have translate german english, don't these in english)

i don't see problem. has idea?

kind regards

in code, listitem isn't instance of secondclass*, it's instance of iterator of secondclass*. have dereference iterator access underlying object. loop should like:

for(listitem = deplist.begin(); listitem != deplist.end(); ++listitem) {     firstclass* theobject = (*listitem)->getthelistobject(); //dereference iterator,                                                               //then call method.     std::cout << theobject->name(); }
