An entity class that wraps converted data, conversion status, and the offset for appending the header and body signature to the converted data. An instance of this class may be created two ways by the drm framework: a) a call to DrmManagerClient.ConvertData(int, System.Byte[]) and b) a call to DrmManagerClient.CloseConvertSession(int). An valid offset value is provided only from a success call to DrmManagerClient.CloseConvertSession(int).
