                                               ObjectInspector inspector)

Description copied from class: AbstractSerDe

Serialize an object by navigating inside the Object with the ObjectInspector. In most cases, the return value of this function will be constant since the function will reuse the Writable object. If the client wants to keep a copy of the Writable, the client needs to clone the returned value.
