org.apache.cocoon.components.pipeline.ProcessingPipeline
A ProcessingPipeline produces the response for a given request. It is assembled according to the commands in the sitemap and can either collect a Reader and let it produce a character stream or connect a Generator with zero or more Transformers and a Serializer and let them produce the byte stream. This pipeline uses SAX events for communication. A ProcessingPipeline is Recomposable since the ComponentManager used to get the generato, transformers etc. depends on the pipeline assembly engine where they are defined (i.e. a given sitemap file). @author Carsten Ziegeler @author Giacomo Pati @version CVS $Id: ProcessingPipeline.java,v 1.2 2003/03/12 09:10:07 jefft Exp $
