This class is available for the OPUS Blackboard API. The initial OPUS 2.0 release is described here

Constructors:

Osf( )
~Osf( )

Methods:

search_mask( )	fill non-unique Field's with search character
mask( )	fill non-unique Field's with pad character fill non-unique Field's with provided character
search_fill_all( )	fill all Field's with search characters

Description

Class Osf defines an OSF object for OPUS applications. OSF entries contain the following field objects:

       Dataset, Obs_stat, Data_id, Dcf_num, Obs_cmd, and Time_stamp.

Clients of the OAPI should refer to any specific OSF implementation through a pointer to this type. The actual OSF will be a more derived type that handles the specifics for some storage medium. By referring to all OSF's through a pointer to this type, OAPI client code isolates itself from the implementation details.
