      • service

        public AbstractEndpoint.Handler.SocketState service​(SocketWrapperBase<?> socketWrapper)
                                             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:
        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

      • 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 provides the server port from the local port.

        Overrides:
        populatePort in class AbstractProcessor

      • 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

      • sslReHandShake

        protected final void sslReHandShake()
                             throws IOException
        Description copied from class: AbstractProcessor
        Processors that can perform a TLS re-handshake (e.g. HTTP/1.1) should override this method and implement the re-handshake.
        Overrides:
        sslReHandShake in class AbstractProcessor
        Throws:
        IOException - If authentication is required then there will be I/O with the client and this exception will be thrown if that goes wrong

      • getUpgradeToken

        public UpgradeToken getUpgradeToken()

        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.
