ensureInSession

@Deprecated
@CheckReturnValue
protected O ensureInSession(O entity)

Deprecated.

avoid using this if possible and ensure that all operations are properly enclosed by a single Hibernate session

Ensure that a given entity is in the current session.

If not found in the current session, it will be retrieved from the persistent storage.

ensureInSession

@Deprecated
@CheckReturnValue
protected Collection<O> ensureInSession(Collection<O> entities)

Deprecated.

avoid using this if possible and ensure that all operations are properly enclosed by a single Hibernate session

Ensure that a collection of entities are in the current session.

Implementation note: if all entities are already in the session - or are transient, this call is very fast and does not involve any database interaction, otherwise the persistent entities are fetched in bulk.
