There is nothing wrong with directly implementing the FieldHandler
interface, however I think the best approach is to extend either
GeneralizedFieldHandler or AbstractFieldHandler...
Extending GeneralizedFieldHandler will allow you to write re-usable
FieldHandlers, otherwise your FieldHandler will most likely be for a
specific field within a specific Class.
Extending AbstractFieldHandler will allow you access to the
XMLFieldDescriptor which has certain information about the field which
may be utilized by your FieldHandler.
(Note: GeneralizedFieldHandler extends AbstractFieldHandler)
If you want to implement FieldHandler directly, then create a base
FieldHandler class that all your FieldHandlers can extend. That way if
the FieldHandler interface changes in the future you can minimize the
changes needed when upgrading to a newer version of Castor.

I have been creating field handlers by implementing the FieldHandler
interface. Is this correct?
But I have seen FieldHandlers created by extending
GeneralizedFieldHandler. Is there a correct use of either of the two for
different scenarios?
I appreciate some help.
Thanks,
Christine
