Package io.undertow.io

Class UndertowOutputStream

java.lang.Object

java.io.OutputStream

io.undertow.io.UndertowOutputStream

All Implemented Interfaces:

BufferWritableOutputStream, java.io.Closeable, java.io.Flushable, java.lang.AutoCloseable

public class UndertowOutputStream
extends java.io.OutputStream
implements BufferWritableOutputStream

Buffering output stream that wraps a channel.

This stream delays channel creation, so if a response will fit in the buffer it is not necessary to set the content length header.
