public class AspectGenerator

implements org.apache.cocoon.caching.CacheableProcessingComponent

This Cocoon generator will generate an internal cocoon request for the next DRI Aspect in the chain. The first time this generator is called it will issue a request for Aspect 2, while it dose this it will store the aspect number in the request object. Every time after the initial use the aspect number is increased and used to generate the next Aspect url. This class extends the FileGenerator and simple intercepts the setup method ignoring anything passed in as the generators source and determines it's own source based upon the current Aspect state.
