ADF was the original database manager for CGNS. As a result, the structure of a CGNS database as described in the SIDS File Mapping parallels closely the functionality of the ADF library. The hierarchical nature, and concept of a node and a link were taken directly from ADF. The ADF database manager is always shipped and built along with the CGNS library.
There is a brief description of ADF; for
further details consult the ADF User's Guide.
The user's guide defines the structure of an ADF file, and describes in
detail the ADF Core, a library of low-level routines used
to store and retrieve data in an ADF file.
Note: As of CGNS Version 3.1, the ADF core
routines have been superseded by the
CGIO interface routines, and any new
development should use those instead.
The complete ADF Implementation in HTML form
is available for installation on a local system.
