public abstract class Workflow

extends java.lang.Object

This class serves as the key class in the httpRequest processing framework to extend when creating specific request processing workflows and work steps. It allows the user to hook into the framework and perform workflow/step specific actions after data is mapped but before the HTTP output page is displayed.

This class also wraps the HTTP request, so you can always have direct access to any servlet information should the Processor class not map enough information for you.
