| class TFrameFormatBase |
The base class for TFrameFormat. Users implement specific frame formats by deriving from this class. Symbian provides a particular implementation in the TFrameFormat class. Each class derived from this class should be identified by a unique UID value, denoting its type. All subclasses should provide implementations of DuplicateL().
