The BreakConnect method releases a pin from a connection.
virtual HRESULT BreakConnect( PIN_DIRECTION dir );
Member of the PIN_DIRECTION enumerated type, specifying which pin connection was broken (input or output).
The CTransformInputPin::BreakConnect and CTransformOutputPin::BreakConnect methods call this method when a pin connection is broken. This method does nothing in the base class. If you override the CheckConnect method, override this method to release any resources obtained in the CheckConnect method, including interface pointers.
