Class RoutablePrintWriter

java.lang.Object

      java.io.PrintWriter
          com.atlassian.gzipfilter.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.
