The CTransInPlaceInputPinclass implements the input pin of a transform-inplace filter ( CTransInPlaceFilter). This is part of a transform filter that transforms data in place rather than making a copy of it. The CTransInPlaceFilter::InputPinmember function returns a pointer to CTransInPlaceInputPinobject.
Typically, you can create objects of a class derived from CTransInPlaceInputPinwithout modifying this class. That is, you can usually override member functions in the CTransInPlaceFilterclass that member functions of the CTransInPlaceInputPinclass call, and not have to derive your own classes for either of the pin classes.
However, if you want to override this class and derive your filter class from CTransInPlaceFilter, you must override the CTransInPlaceFilter::GetPinmember function to create pins of your derived class.
