Direct Known Subclasses:

CascadeLoadPlanBuilderStrategy

public class SingleRootReturnLoadPlanBuilderStrategy
extends AbstractLoadPlanBuilderStrategy
implements LoadPlanBuilderStrategy

LoadPlanBuilderStrategy implementation used for building LoadPlans with a single processing RootEntity LoadPlan building. Really this is a single-root LoadPlan building strategy for building LoadPlans for:

• entity load plans
• cascade load plans
• collection initializer plans
