Package org.hibernate.persister.collection.mutation
Defines support for performing mutation operations against collections.
- API Note:
- The names used here are logical. E.g. "inserting a row" may actually
execute an UPDATE statement instead of an INSERT. This is generally
delineated based on whether there is a collection table involved or
not. In terms of our usual model, this breaks down to the distinction
between
BasicCollectionPersisterandOneToManyPersister.
