ch.tocco.nice2.dms.impl.security.NodeChildrenCollectionInitializer

All Implemented Interfaces:

CollectionInitializer

@Component
public class NodeChildrenCollectionInitializer
extends AbstractCollectionInitializer

A custom CollectionInitializer that initializes the sub resources of a folder. It resolves the primary keys of the relation in privileged mode first and sets the result as the upper bound of the unprivileged query using the QueryHints.QUERY_BY_KEYS hint. This hint allows the PermissionMatrixEvaluationService to optimize a subquery which results in much better performance.
