  • Method Details

    • process

      public AbstractEndpoint.Handler.SocketState process(SocketWrapperBase<?> socketWrapper, SocketEvent status) throws IOException
      Description copied from interface: Processor
      Process a connection. This is called whenever an event occurs (e.g. more data arrives) that allows processing to continue for a connection that is not currently being processed.
      Specified by:
      process in interface Processor
      Parameters:
      socketWrapper - The connection to process
      status - The status of the connection that triggered this additional processing
      Returns:
      The state the caller should put the socket in when this method returns
      Throws:
      IOException - If an I/O error occurs during the processing of the request

    • addDispatch

      public void addDispatch(DispatchType dispatchType)

    • getIteratorAndClearDispatches

      public Iterator<DispatchType> getIteratorAndClearDispatches()

    • clearDispatches

      protected void clearDispatches()

    • logAccess

      protected void logAccess(SocketWrapperBase<?> socketWrapper) throws IOException
      Add an entry to the access log for a failed connection attempt.
      Parameters:
      socketWrapper - The connection to process
      Throws:
      IOException - If an I/O error occurs during the processing of the request

    • service

      protected abstract AbstractEndpoint.Handler.SocketState service(SocketWrapperBase<?> socketWrapper) throws IOException
      Service a 'standard' HTTP request. This method is called for both new requests and for requests that have partially read the HTTP request line or HTTP headers. Once the headers have been fully read this method is not called again until there is a new HTTP request to process. Note that the request type may change during processing which may result in one or more calls to dispatch(SocketEvent). Requests may be pipe-lined.
      Parameters:
      socketWrapper - The connection to process
      Returns:
      The state the caller should put the socket in when this method returns
      Throws:
      IOException - If an I/O error occurs during the processing of the request

    • dispatch

      protected abstract AbstractEndpoint.Handler.SocketState dispatch(SocketEvent status) throws IOException
      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.
      Parameters:
      status - The event to process
      Returns:
      The state the caller should put the socket in when this method returns
      Throws:
      IOException - If an I/O error occurs during the processing of the request

    • asyncPostProcess

      protected abstract AbstractEndpoint.Handler.SocketState asyncPostProcess() throws IOException
      Calls the post process of the async state machine.
      Returns:
      The state the caller should put the socket in when this method returns
      Throws:
      IOException - If an I/O error occurs during the processing of the request

    • getLog

      protected abstract Log getLog()
      Returns:
      the logger associated with this processor type
