All Implemented Interfaces:

Closeable, Flushable, 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.
