Class RoutablePrintWriter

java.lang.Object
  java.io.Writer
      java.io.PrintWriter
          org.sitemesh.webapp.contentfilter.io.RoutablePrintWriter

All Implemented Interfaces:

Closeable, Flushable, Appendable

public class RoutablePrintWriter
extends PrintWriter

Provides a PrintWriter that routes through to another PrintWriter, 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.
