CTransInPlaceInputPin Class
.gif)
This class 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::InputPin member function returns a pointer to CTransInPlaceInputPin object.
Typically, you can create objects of a class derived from CTransInPlaceInputPin without modifying this class. That is, you can usually override member functions in the CTransInPlaceFilter class that member functions of the CTransInPlaceInputPin class 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::GetPin member function to create pins of your derived class.
