All Implemented Interfaces:

Closeable, Flushable, Appendable, AutoCloseable
```
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.
