Examples of org.eclipse.persistence.queries.LoadGroup

org.eclipse.persistence.queries.LoadGroup
Purpose: Used to load specified relationship attributes and nested relationship attributes.
A LoadGroup can be configured for use on a query using {@link ObjectLevelReadQuery#setLoadGroup(LoadGroup)} or in the case of JPAusers with LOAD_GROUP query hint. Alternatively a {@link FetchGroup} could beused with {@link FetchGroup#shouldLoad()} set to true and the FetchGroupconfigured on a query be executed. @see FetchGroup @author ailitchev @since Eclipselink 2.1
