C++ classes for a digital library

摘要

An overall programming interface containing hundreds of application program interfaces (API's) for performing library functions on data objects in a digital client/server library system is simplified through a new, object oriented interface containing a small number of object oriented classes. Object instances created from the object oriented classes have member functions which are invoked by application programs, and the member functions issue appropriate calls to the API's. Information returned from the API's is handled by the calling object and provided to the application program in a simplified form.
