Class RoutableServletOutputStream

java.lang.Object

java.io.OutputStream

javax.servlet.ServletOutputStream

com.opensymphony.module.sitemesh.filter.RoutableServletOutputStream

All Implemented Interfaces:

java.io.Closeable, java.io.Flushable, java.lang.AutoCloseable

public class RoutableServletOutputStream
extends javax.servlet.ServletOutputStream

Provides a ServletOutputStream that routes through to another ServletOutputStream, however the destination can be changed at any point. The destination can be passed in using a factory, so it will not be created until it's actually needed.
