 *  Base interface of all OpenFlow objects (e.g., messages, actions, stats, etc.)

 *  All objects have a length and can be read and written from a buffer.
 *  When writing, the length field is dynamically updated, so it need not be
 *  managed manually.  However, you can override the auto calculated length with
 *  overrideLength() call, if, for example, you want to intentionally create
 *  malformed packets, for example, for negative testing.
