public class HttpOutputStream

extends javax.servlet.ServletOutputStream

HTTP output stream

Implements ServletOutputStream

Notes

Implements a callback to the HttpResponse to trigger a writeHeader on the first output. Not if HttpFilters are used, this may result in replaceOut being called on this HttpOutputStream.

The path that a single call to write on HttpOutputStream can be delegated to the following output streams:

  ---> HttpOutputSteam.out --> Filter out 1 --> ... -> Filter out N
                                                               |
