 *         This interface provides abstraction for different modify operation handlers and
 *         can be used for optimization. For example some simple modification operations can be done
 *         without merging full entity state, which should save a few select queries during merge
 *         (in case of complex objects it could be 10-20 select queries).
 *         <p/>
 *         Instances of his interface should be stateless.
