Class PipelineHandler

java.lang.Object
  com.oroad.stxx.plugin.PipelineHandler

public class PipelineHandler

extends java.lang.Object

Parses and stores the transforms. Matches the request, through a Selector, to a transform which converts the XML into its final form. Usually, this means the XML is transformed by one or more XSL files to create HTML.

This plugin supports two different ways to define transforms. The first, present since v1.1 uses one transform definition per Struts action mapping. The second uses generic pipeline definitions to match Struts forwards. The first is deprecated and the second is prefered.
