CTransformInputPin Class (Compact 2013)

3/26/2014

CBaseInputPin Class

     CTransformInputPin Class

This class implements the input pin of a simple transform filter. It is the class assigned to the m_pInput data member of the CTransformFilter class.

Typically, you can create objects derived from CTransformFilter without modifying the CTransformInputPin class. That is, you can usually override the member functions in CTransformFilter that are called by member functions of this class. You need not derive your own classes for either of the pin classes.

However, to override this class and have your filter class derived from CTransformFilter, override the CTransformFilter::GetPin member function to create pins of your derived class.
