HQLQueryPlan

public HQLQueryPlan(String hql,
                    boolean shallow,
                    Map<String,Filter> enabledFilters,
                    SessionFactoryImplementor factory)

Constructs a HQLQueryPlan

参数:

hql - The HQL query

shallow - Whether the execution is to be shallow or not

enabledFilters - The enabled filters (we only keep the names)

factory - The factory
