Field Detail

### outputStream

    protected OutputStream outputStream

  Underlying output stream. Note: protected to assist with unit testing

Constructor Detail

### InternalOutputBuffer

    public InternalOutputBuffer(Response response,
                                int headerBufferSize)

  Default constructor.

Method Detail

### setSocketBuffer

    public void setSocketBuffer(int socketBufferSize)

  Set the socket buffer size.

### init

    public void init(SocketWrapper<Socket> socketWrapper,
                     AbstractEndpoint endpoint)
              throws IOException

  Specified by:
    `init` in class `AbstractOutputBuffer<Socket>`
  Throws:
    `IOException`

### flush

    public void flush()
               throws IOException

  Flush the response.

  Overrides:
    `flush` in class `AbstractOutputBuffer<Socket>`
  Throws:
    `IOException` - an underlying I/O error occurred

### recycle

    public void recycle()

  Recycle the output buffer. This should be called when closing the connection.

  Overrides:
    `recycle` in class `AbstractOutputBuffer<Socket>`

### nextRequest

    public void nextRequest()

  End processing of current HTTP request. Note: All bytes of the current request should have been already consumed. This method only resets all the pointers so that we are ready to parse the next HTTP request.

  Overrides:
    `nextRequest` in class `AbstractOutputBuffer<Socket>`

### endRequest

    public void endRequest()
                    throws IOException

  End request.

  Overrides:
    `endRequest` in class `AbstractOutputBuffer<Socket>`
  Throws:
    `IOException` - an underlying I/O error occurred

### sendAck

    public void sendAck()
                 throws IOException

  Send an acknowledgment.

  Specified by:
    `sendAck` in class `AbstractOutputBuffer<Socket>`
  Throws:
    `IOException`

### commit

    protected void commit()
                   throws IOException

  Commit the response.

  Specified by:
    `commit` in class `AbstractOutputBuffer<Socket>`
  Throws:
    `IOException` - an underlying I/O error occurred

### realWriteBytes

    public void realWriteBytes(byte[] cbuf,
                               int off,
                               int len)
                        throws IOException

  Callback to write data from the buffer.

  Specified by:
    `realWriteBytes` in interface `ByteChunk.ByteOutputChannel`
  Throws:
    `IOException`
