Example 7 with ConduitStreamSinkChannel

use of org.xnio.conduits.ConduitStreamSinkChannel in project undertow by undertow-io.

the class HttpServerExchange method getResponseChannel.

/**
     * Get the response channel. The channel must be closed and fully flushed before the next response can be started.
     * In order to close the channel you must first call {@link org.xnio.channels.StreamSinkChannel#shutdownWrites()},
     * and then call {@link org.xnio.channels.StreamSinkChannel#flush()} until it returns true. Alternatively you can
     * call {@link #endExchange()}, which will close the channel as part of its cleanup.
     * <p>
     * Closing a fixed-length response before the corresponding number of bytes has been written will cause the connection
     * to be reset and subsequent requests to fail; thus it is important to ensure that the proper content length is
     * delivered when one is specified.  The response channel may not be writable until after the response headers have
     * been sent.
     * <p>
     * If this method is not called then an empty or default response body will be used, depending on the response code set.
     * <p>
     * The returned channel will begin to write out headers when the first write request is initiated, or when
     * {@link org.xnio.channels.StreamSinkChannel#shutdownWrites()} is called on the channel with no content being written.
     * Once the channel is acquired, however, the response code and headers may not be modified.
     * <p>
     *
     * @return the response channel, or {@code null} if another party already acquired the channel
