Constructs a CTransformFilter object.

Syntax

CTransformFilter(
  TCHAR *pObjectName,
  LPUNKNOWN lpUnk,
  CLSID clsid 
);

Parameters

• pObjectName
  Name given to the CTransformFilter object.

• lpUnk
  Pointer to LPUNKNOWN.

• clsid
  Class identifier of the CTransformFilter class.

Return Value

None.

Remarks

The constructor of the derived class calls this member function.

The pin objects are not created at this time; they are created when calling the CTransformFilter::GetPin member function. Thus the pins (m_pInput and m_pOutput) cannot be referred to in the constructor unless GetPin is first called.

(An external object can find pins only by enumerating them or by calling IBaseFilter::FindPin. These each call GetPin, so the pins are created as soon as they are needed.)
