creates a new factory object for the current stream and stream position.
When activated, the factory will be able to create new DcmInputStream delivering the same data as the current stream. Used to defer loading of value fields until accessed. If no factory object can be created (e.g. because the stream is not seekable), returns NULL.
- Returns:
- pointer to new factory object if successful, NULL otherwise.
Implements DcmInputStream.
