    • flushBufferedWrite

      protected boolean flushBufferedWrite() throws IOException
      Description copied from class: AbstractProcessor
      Flush any pending writes. Used during non-blocking writes to flush any remaining data from a previous incomplete write.
      Specified by:
      flushBufferedWrite in class AbstractProcessor
      Returns:
      true if data remains to be flushed at the end of method
      Throws:
      IOException - If an I/O error occurs while attempting to flush the data

    • dispatchNonBlockingRead

      protected void dispatchNonBlockingRead()
      Description copied from class: AbstractProcessor
      Perform any necessary processing for a non-blocking read before dispatching to the adapter.
      Overrides:
      dispatchNonBlockingRead in class AbstractProcessor

    • dispatchEndRequest

      protected AbstractEndpoint.Handler.SocketState dispatchEndRequest()
      Description copied from class: AbstractProcessor
      Perform any necessary clean-up processing if the dispatch resulted in the completion of processing for the current request.
      Specified by:
      dispatchEndRequest in class AbstractProcessor
      Returns:
      The state to return for the socket once the clean-up for the current request has completed

    • service

      public AbstractEndpoint.Handler.SocketState service(SocketWrapperBase<?> socket) throws IOException
      Description copied from class: AbstractProcessorLight
      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 AbstractProcessorLight.dispatch(SocketEvent). Requests may be pipe-lined.
      Specified by:
      service in class AbstractProcessorLight
      Parameters:
      socket - 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

    • recycle

      public void recycle()
      Description copied from interface: Processor
      Recycle the processor, ready for the next request which may be on the same connection or a different connection.
      Specified by:
      recycle in interface Processor
      Overrides:
      recycle in class AbstractProcessor

    • 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.

    • refillReadBuffer

      protected boolean refillReadBuffer(boolean block) throws IOException
      Get more request body data from the web server and store it in the internal buffer.
      Parameters:
      block - true if this is blocking IO
      Returns:
      true if there is more data, false if not.
      Throws:
      IOException - An IO error occurred

    • populateHost

      protected void populateHost()
      Called when a host header is not present in the request (e.g. HTTP/1.0). It populates the server name with appropriate information. The source is expected to vary by protocol.

      The default implementation is a NO-OP.

      This implementation populates the server name from the local name provided by the AJP message.

      Overrides:
      populateHost in class AbstractProcessor

    • populatePort

      protected void populatePort()
      Called when a host header is not present or is empty in the request (e.g. HTTP/1.0). It populates the server port with appropriate information. The source is expected to vary by protocol.

      The default implementation is a NO-OP.

      This implementation populates the server port from the local port provided by the AJP message.

      Overrides:
      populatePort in class AbstractProcessor

    • prepareResponse

      protected final void prepareResponse() throws IOException
      When committing the response, we have to validate the set of headers, as well as setup the response filters.
      Specified by:
      prepareResponse in class AbstractProcessor
      Throws:
      IOException - IO exception during commit

    • flush

      protected final void flush() throws IOException
      Description copied from class: AbstractProcessor
      Callback to write data from the buffer.
      Specified by:
      flush in class AbstractProcessor
      Throws:
      IOException - IO exception during the write

    • finishResponse

      protected final void finishResponse() throws IOException
      Description copied from class: AbstractProcessor
      Finish the current response.
      Specified by:
      finishResponse in class AbstractProcessor
      Throws:
      IOException - IO exception during the write

    • ack

      protected final void ack(ContinueResponseTiming continueResponseTiming)
      Description copied from class: AbstractProcessor
      Process acknowledgment of the request.
      Specified by:
      ack in class AbstractProcessor

      setSwallowResponse in class AbstractProcessor

    • disableSwallowRequest

      protected final void disableSwallowRequest()
      Description copied from class: AbstractProcessor
