    31 

    32 This is provided as a way of retaining BC for the CObexClient and 

    33 CObexServer classes.

    34 

    35 This class implements the MObexNotifyExtend interface which is provided

    36 to the transport.  Functions can safely be added to MObexNotifyExtend to 

    37 allow the transport to provide additional notifications in future without

    38 altering the vtable for the published classes.  

    39 

    40 A CObex owns a CObexNotifyHandlerBase.  The CObexNotifyHandler base

    41 should not be instantiated directly, instead one of the derived classes

    42 should be used.  The derived class then knows the type of the CObex

    43 object created it, as the constructor will require an appropriately

    44 derived type.  This allows the non-virtual functions in the appropriate

    45 class to be called to handle notifications.

    46 

    47 Functions that are generic CObex functions, rather than functions that

    48 are handled differently by CObexClient and CObexServer, may be implemented

    49 in the base class.
