 * 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.
