      Description copied from interface: `EndPoint`
      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.
      Specified by:
        `flush` in interface `EndPoint`
      Parameters:
        `buffer` - The buffer to flush. This buffers getIndex is updated.
      Returns:

      Description copied from interface: `EndPoint`
      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.
      Specified by:
        `flush` in interface `EndPoint`
      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`

      Specified by:
        `getRemoteAddr` in interface `EndPoint`

      Description copied from interface: `EndPoint`
      Flush any buffered output. May fail to write all data if endpoint is non-blocking
      Specified by:

    - #### getMaxIdleTime

          public int getMaxIdleTime()

      Description copied from interface: `EndPoint`
      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.

      Specified by:
        `getMaxIdleTime` in interface `EndPoint`
      Returns:
        the max idle time in ms or if ms <= 0 implies an infinite timeout

    - #### setMaxIdleTime

          public void setMaxIdleTime(int timeMs)

      Description copied from interface: `EndPoint`
      Set the max idle time.
      Specified by:
        `setMaxIdleTime` in interface `EndPoint`
      Parameters:
        `timeMs` - the max idle time in MS. Timeout <= 0 implies an infinite timeout
      Throws:
        `IOException` - if the timeout cannot be set.

        `StreamEndPoint.setMaxIdleTime(int)`
