GetGenerationId method
Retrieves the current generation ID for the object.
Syntax
HRESULT retVal = object.GetGenerationId(pID);
Parameters
pID [out]
Type: unsigned longPointer to the location to store the generation ID.
Remarks
Calling methods can use the generation ID to determine whether cached parameters are still valid. Transforms will examine all input generation IDs during this call. If any have changed, they increment their own generation ID and cache the input's new generation ID.
