0027 //! This package define  CAF main classes.
0028 //!
0029 //! * The standard application root class
0030 //!
0031 //! * The standard document which contains data
0032 //!
0033 //! * The external reference mechanism between documents
0034 //!
0035 //! * Attributes for Document management
0036 //! Standard documents offer you a ready-to-use
0037 //! document containing a TDF-based data
0038 //! structure. The documents themselves are
0039 //! contained in a class inheriting from
0040 //! TDocStd_Application which manages creation,
0041 //! storage and retrieval of documents.
0042 //! You can implement undo and redo in your
0043 //! document, and refer from the data framework of
0044 //! one document to that of another one. This is
0045 //! done by means of external link attributes, which
0046 //! store the path and the entry of external links. To
0047 //! sum up, standard documents alone provide
0048 //! access to the data framework. They also allow
0049 //! you to:
0050 //! -   Update external links
0051 //! -   Manage the saving and opening of data
0052 //! -   Manage undo/redo functionality.
0053 //! Note
0054 //! For information on the relations between this
0055 //! component of OCAF and the others, refer to the
0056 //! OCAF User's Guide.
