      • setBufferStatus

        public void setBufferStatus​(SessionBufferStatus bufferStatus)
        Description copied from interface: IOSession
        Quite often I/O sessions need to maintain internal I/O buffers in order to transform input / output data prior to returning it to the consumer or writing it to the underlying channel. Memory management in HttpCore NIO is based on the fundamental principle that the data consumer can read only as much input data as it can process without having to allocate more memory. That means, quite often some input data may remain unread in one of the internal or external session buffers. The I/O reactor can query the status of these session buffers, and make sure the consumer gets notified correctly as more data gets stored in one of the session buffers, thus allowing the consumer to read the remaining data once it is able to process it

        I/O sessions can be made aware of the status of external session buffers using the SessionBufferStatus interface.

        Specified by:
        setBufferStatus in interface IOSession

      • setAttribute

        public void setAttribute​(String name,
                         Object obj)
        Description copied from interface: IOSession
        This method can be used to associate a particular object with the session by the given attribute name.

        I/O sessions are not bound to an execution thread, therefore one cannot use the context of the thread to store a session's state. All details about a particular session must be stored within the session itself.

        Specified by:
        setAttribute in interface IOSession
        Parameters:
        name - name of the attribute.
        obj - value of the attribute.

      • getLastAccessTime

        public long getLastAccessTime()

      • getSocket

        public Socket getSocket()
        Description copied from interface: SocketAccessor
        Return the underlying socket
        Specified by:

        Returns:
        - the underlying Socket, may be null.
