    Modifier and Type | Method and Description
    --- | ---
    `void` | `close()`
    `AbstractEndpoint.Handler.SocketState` | `dispatch(SocketEvent status)` Process an in-progress request that is not longer in standard HTTP mode.
    `ServletInputStream` | `getInputStream()` Provides access to the `ServletInputStream` for reading data from the client.

- - ### Constructor Detail

    - #### UpgradeProcessorInternal

          public UpgradeProcessorInternal(SocketWrapperBase<?> wrapper,
                                          UpgradeToken upgradeToken)

  - ### Method Detail

    - #### dispatch

          public AbstractEndpoint.Handler.SocketState dispatch(SocketEvent status)

      Description copied from class: `AbstractProcessorLight`
      Process an in-progress request that is not longer in standard HTTP mode. Uses currently include Servlet 3.0 Async and HTTP upgrade connections. Further uses may be added in the future. These will typically start as HTTP requests.
      Specified by:
        `dispatch` in class `AbstractProcessorLight`
      Parameters:
        `status` - The event to process
      Returns:
        The state the caller should put the socket in when this method returns

    - #### setSslSupport

          public final void setSslSupport(SSLSupport sslSupport)

      Description copied from interface: `Processor`
      Set the SSL information for this HTTP connection.
      Parameters:
        `sslSupport` - The SSL support object to use for this connection

    - #### pause

          public void pause()

      Description copied from interface: `Processor`
      Informs the processor that the underlying I/O layer has stopped accepting new connections. This is primarily intended to enable processors that use multiplexed connections to prevent further 'streams' being added to an existing multiplexed connection.

    - #### getLog

          protected Log getLog()

      Specified by:
        `getLog` in class `AbstractProcessorLight`

    - #### timeoutAsync

          public void timeoutAsync(long now)

      Description copied from interface: `Processor`
      Check this processor to see if the timeout has expired and process a timeout if that is that case.

      Note: The name of this method originated with the Servlet 3.0 asynchronous processing but evolved over time to represent a timeout that is triggered independently of the socket read/write timeouts.

      Specified by:
        `timeoutAsync` in interface `Processor`
      Overrides:
        `timeoutAsync` in class `UpgradeProcessorBase`
      Parameters:
        `now` - The time (as returned by `System.currentTimeMillis()` to use as the current time to determine whether the timeout has expired. If negative, the timeout will always be treated as ifq it has expired.

    - #### hasAsyncIO

          public boolean hasAsyncIO()

    - #### close

          public void close()
                     throws Exception

      Throws:
        `Exception`

    - #### getInputStream

          public ServletInputStream getInputStream()
                                            throws IOException

      Description copied from interface: `javax.servlet.http.WebConnection`
      Provides access to the `ServletInputStream` for reading data from the client.
      Returns:
        the input stream
      Throws:
        `IOException` - If an I/O occurs while obtaining the stream

    - #### getOutputStream

          public ServletOutputStream getOutputStream()
                                              throws IOException

      Description copied from interface: `javax.servlet.http.WebConnection`
      Provides access to the `ServletOutputStream` for writing data to the client.
      Returns:
        the output stream
      Throws:
        `IOException` - If an I/O occurs while obtaining the stream
