Examples of oracle.toplink.essentials.descriptors.FetchGroupManager

oracle.toplink.essentials.descriptors.FetchGroupManager

Purpose: The fetch group manager controls the named fetch groups defined at the descriptor level. TopLink supports multiple, overlapped fetch groups, optionally with one of them as the default fetch group. The domain object must implement oracle.toplink.essentials.queryframework.FetchGroupTracker interface, in order to make use of the fetch group performance enhancement feature. Please refer to FetchGroup class for the prons and cons of fetch group usage. @see oracle.toplink.essentials.queryframework.FetchGroup @see oracle.toplink.essentials.queryframework.FetchGroupTracker @author King Wang @since TopLink 10.1.3.

            mapping = session.getDescriptor(object.getClass()).getObjectBuilder().getMappingForAttributeName(getName());
        }


        //fetch group support
        if (mapping.getDescriptor().hasFetchGroupManager()) {
            FetchGroupManager fetchGroupMgr = mapping.getDescriptor().getFetchGroupManager();
            if (fetchGroupMgr.isPartialObject(object) && (!fetchGroupMgr.isAttributeFetched(object, mapping.getAttributeName()))) {
                //the conforming attribute is not fetched, simply throw exception
                throw QueryException.cannotConformUnfetchedAttribute(mapping.getAttributeName());
            }
        }
