Filter Directives

Filter directives use Robot Application Functions (RAFs) to perform operations. Their use and flow of execution is similar to that of NSAPI directives and Server Application Functions (SAFs) in the file obj.conf. Like NSAPI and SAF, data are stored and transferred using parameter blocks, also called pblocks.

There are six robot directives, or RAF classes, corresponding to the filtering phases and operations listed below. See Stages in the Filter Process for more information on these phases.

Each directive has its own robot application functions. For example, use filtering functions with the Metadata and Data directives, enumeration functions with the Enumerate directive, generation functions with the Generate directive, and so on.

The built-in robot application functions and instructions for writing your own robot application functions are explained in the Sun Java System Portal Server 7.1 Developer's Guide.
