    - #### shutdownInput

          void shutdownInput()
                             throws IOException

      Shutdown any backing input stream associated with the endpoint
      Throws:
        `IOException`

    - #### isInputShutdown

          boolean isInputShutdown()

    - #### close

          void close()
                     throws IOException

      Close any backing stream associated with the endpoint
      Throws:
        `IOException`

    - #### fill

          int fill(Buffer buffer)
                   throws IOException

      Fill the buffer from the current putIndex to it's capacity from whatever byte source is backing the buffer. The putIndex is increased if bytes filled. The buffer may chose to do a compact before filling.
      Returns:
        an `int` value indicating the number of bytes filled or -1 if EOF is reached.
      Throws:
        `EofException` - If input is shutdown or the endpoint is closed.
        `IOException`

    - #### flush

          int flush(Buffer buffer)
                    throws IOException

      Flush the buffer from the current getIndex to it's putIndex using whatever byte sink is backing the buffer. The getIndex is updated with the number of bytes flushed. Any mark set is cleared. If the entire contents of the buffer are flushed, then an implicit empty() is done.
      Parameters:
        `buffer` - The buffer to flush. This buffers getIndex is updated.
      Returns:
        the number of bytes written
      Throws:
        `EofException` - If the endpoint is closed or output is shutdown.
        `IOException`

    - #### flush

          int flush(Buffer header,
                  Buffer buffer,
                  Buffer trailer)
                    throws IOException

      Flush the buffer from the current getIndex to it's putIndex using whatever byte sink is backing the buffer. The getIndex is updated with the number of bytes flushed. Any mark set is cleared. If the entire contents of the buffer are flushed, then an implicit empty() is done. The passed header/trailer buffers are written before/after the contents of this buffer. This may be done either as gather writes, as a poke into this buffer or as several writes. The implementation is free to select the optimal mechanism.
      Parameters:
        `header` - A buffer to write before flushing this buffer. This buffers getIndex is updated.
        `buffer` - The buffer to flush. This buffers getIndex is updated.
        `trailer` - A buffer to write after flushing this buffer. This buffers getIndex is updated.
      Returns:
        the total number of bytes written.
      Throws:
        `IOException`

    - #### getLocalAddr

          String getLocalAddr()

      Returns:
        The local IP address to which this `EndPoint` is bound, or `null` if this `EndPoint` does not represent a network connection.

    - #### getLocalHost

          String getLocalHost()

      Returns:
        The local host name to which this `EndPoint` is bound, or `null` if this `EndPoint` does not represent a network connection.

    - #### getLocalPort

          int getLocalPort()

      Returns:
        The local port number on which this `EndPoint` is listening, or `0` if this `EndPoint` does not represent a network connection.

    - #### getRemoteAddr

          String getRemoteAddr()

      Returns:
        The remote IP address to which this `EndPoint` is connected, or `null` if this `EndPoint` does not represent a network connection.

    - #### getRemoteHost

          String getRemoteHost()

      Returns:
        The host name of the remote machine to which this `EndPoint` is connected, or `null` if this `EndPoint` does not represent a network connection.

    - #### getRemotePort

          int getRemotePort()

      Returns:
        The remote port number to which this `EndPoint` is connected, or `0` if this `EndPoint` does not represent a network connection.

    - #### isBlocking

          boolean isBlocking()

    - #### blockReadable

          boolean blockReadable(long millisecs)
                                throws IOException

      Throws:
        `IOException`

    - #### blockWritable

          boolean blockWritable(long millisecs)
                                throws IOException

      Throws:
        `IOException`

    - #### isOpen

          boolean isOpen()

    - #### getTransport

          Object getTransport()

      Returns:
        The underlying transport object (socket, channel, etc.)

    - #### flush

          void flush()
                     throws IOException

      Flush any buffered output. May fail to write all data if endpoint is non-blocking
      Throws:
        `EofException` - If the endpoint is closed or output is shutdown.
        `IOException`

    - #### getMaxIdleTime

          int getMaxIdleTime()

      Get the max idle time in ms.

      The max idle time is the time the endpoint can be idle before extraordinary handling takes place. This loosely corresponds to the `Socket.getSoTimeout()` for blocking connections, but `AsyncEndPoint` implementations must use other mechanisms to implement the max idle time.

      Returns:
        the max idle time in ms or if ms <= 0 implies an infinite timeout

    - #### setMaxIdleTime

          void setMaxIdleTime(int timeMs)
                              throws IOException

      Set the max idle time.
      Parameters:
        `timeMs` - the max idle time in MS. Timeout <= 0 implies an infinite timeout
      Throws:
        `IOException` - if the timeout cannot be set.
