A strategy for persisting a collection role. Defines a contract between the persistence strategy and the actual persistent collection framework and session. Does not define operations that are required for querying collections, or loading by outer join.

Implements persistence of a collection instance while the instance is referenced in a particular role.

This class is highly coupled to the PersistentCollection hierarchy, since double dispatch is used to load and update collection elements.

May be considered an immutable view of the mapping object
