GetGenerationId method

  • Article

Retrieves the current generation ID for the object.

Syntax

HRESULT retVal = object.GetGenerationId(pID);

Parameters

  • pID [out]
    Type: unsigned long

    Pointer 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.
