C++ - when are non-pointers class member destroyed?

Question

Suppose I have this code... ``` class GraphFactory : public QObject { private: QMap factory_; public: virtual ~GraphFactory(); }; GraphFactory::~GraphFactory() { // Free up the graph creators QMap::iterator itr; for (itr = factory_.begin(); itr != factory_.end(); itr++) { IGraphCreator * creator = itr.value(); delete creator; creator = NULL; } } ``` When is the QMap factory_ destroyed? Before the call to the destructor, or during the destructor? (I understand that the destructor will be called when an instance of GraphFactory goes out of scope. But when are the non-pointers member destroyed?) Edit: I am getting invalid values for the factory_ map when it reaches the destructor. A break point shows that the value wouldn't have tampered with the value stored inside the QMap.

Accepted Answer

It'll be destructed after the destructor code gets executed

The idea is to have access to your members in the destructor code so they get destroyed after it gets executed.
