Isn't an Iterator in c++ a kind of a pointer?
- by Bilthon
Ok this time I decided to make a list using the STL. I need to create a dedicated TCP socket for each client. So everytime I've got a connection, I instantiate a socket and add a pointer to it on a list.
list<MyTcp*> SocketList; //This is the list of pointers to sockets
list<MyTcp*>::iterator it; //An iterator to the list of pointers to TCP sockets.
Putting a new pointer to a socket was easy, but now every time the connection ends I should disconnect the socket and delete the pointer so I don't get a huge memory leak, right? well.. I thought I was doing ok by setting this:
it=SocketList.begin();
while( it != SocketList.end() ){
if((*it)->getClientId() == id){
pSocket = it; // <-------------- compiler complains at this line
SocketList.remove(pSocket);
pSocket->Disconnect();
delete pSocket;
break;
}
}
But the compiler is saying this:
error: invalid cast from type ‘std::_List_iterator<MyTcp*>’ to type ‘MyTcp*’
Can someone help me here? i thought I was doing things right, isn't an iterator at any given time just pointing to one of the elements of the set? how can I fix it?
