Class PrivilegedCollectionInitializer

java.lang.Object

ch.tocco.nice2.persist.core.api.hibernate.interceptor.AbstractCollectionInitializer

ch.tocco.nice2.persist.security.impl.hibernate.interceptor.PrivilegedCollectionInitializer

All Implemented Interfaces:

CollectionInitializer

@Component
public class PrivilegedCollectionInitializer
extends AbstractCollectionInitializer

CollectionInitializer that optimizes the query for the contributed entities (e.g. Email_archive).

Entities are loaded privileged and are then checked using a ListGuard. Even though this executes more queries it is a lot faster, because the single query would create many large joins due to the ACL rules for the contributed entities.
