Class AbstractXMLByteStreamInterpreter

java.lang.Object
  extended by org.apache.cocoon.components.sax.AbstractXMLByteStreamInterpreter
All Implemented Interfaces:
XMLByteStreamConstants, XMLProducer
Direct Known Subclasses:
XMLByteStreamInterpreter, XMLInputStreamInterpreter

public abstract class AbstractXMLByteStreamInterpreter
extends Object
implements XMLProducer, XMLByteStreamConstants

This a simple xml compiler which takes a byte array as input. If you want to reuse this interpreter make sure to call first recycle() and then set the new consumer for the sax events.
