Class AbstractXMLByteStreamInterpreter

java.lang.Object
  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.
