- - ### Constructor Detail

    - #### InternalNioInputBuffer

          public InternalNioInputBuffer(Request request,
                                int headerBufferSize)

      Alternate constructor.

  - ### Method Detail

    - #### recycle

          public void recycle()

      Recycle the input buffer. This should be called when closing the connection.
      Overrides:
        `recycle` in class `AbstractInputBuffer<NioChannel>`

    - #### 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 `AbstractInputBuffer<NioChannel>`

    - #### parseRequestLine

          public boolean parseRequestLine(boolean useAvailableDataOnly)
                                   throws IOException

      Read the request line. This function is meant to be used during the HTTP request header parsing. Do NOT attempt to read the request body using it.
      Specified by:
        `parseRequestLine` in class `AbstractInputBuffer<NioChannel>`
      Returns:
        true if data is properly fed; false if no data is available immediately and thread should be freed
      Throws:
        `IOException` - If an exception occurs during the underlying socket read operations, or if the given buffer is not big enough to accommodate the whole line.

    - #### parseHeaders

          public boolean parseHeaders()
                               throws IOException

      Parse the HTTP headers.
      Specified by:
        `parseHeaders` in class `AbstractInputBuffer<NioChannel>`
      Throws:
        `IOException`

    - #### getParsingRequestLinePhase

          public int getParsingRequestLinePhase()

    - #### init

          protected void init(SocketWrapper<NioChannel> socketWrapper,
                  AbstractEndpoint<NioChannel> endpoint)
                       throws IOException

      Specified by:
        `init` in class `AbstractInputBuffer<NioChannel>`
      Throws:
        `IOException`

    - #### fill

          protected boolean fill(boolean block)
                          throws IOException,
                                 EOFException

      Fill the internal buffer using data from the underlying input stream.
      Specified by:
        `fill` in class `AbstractInputBuffer<NioChannel>`
      Returns:
        false if at end of stream
      Throws:
        `IOException`
        `EOFException`

    - #### fill

          protected boolean fill(boolean timeout,
                     boolean block)
                          throws IOException,
                                 EOFException

      Throws:
        `IOException`
