直接已知子类:

CascadeStyleLoadPlanBuildingAssociationVisitationStrategy

public class FetchStyleLoadPlanBuildingAssociationVisitationStrategy
extends AbstractLoadPlanBuildingAssociationVisitationStrategy

LoadPlanBuildingAssociationVisitationStrategy implementation used for building LoadPlans based on metamodel-defined fetching. Built LoadPlans contain a single root return object, either an EntityReturn or a CollectionReturn.
