获取聚合根Handle时如果是级联继承，是否应该将子类以及父类的Handle一起加载

[xbOnline]

    public Action<IAggregateRoot, IDomainEvent> GetInternalEventHandler(Type aggregateRootType, Type eventType)
    {
        IDictionary<Type, Action<IAggregateRoot, IDomainEvent>> eventHandlerDic;
        if (!_mappings.TryGetValue(aggregateRootType, out eventHandlerDic)) return null;
        Action<IAggregateRoot, IDomainEvent> eventHandler;
        return eventHandlerDic.TryGetValue(eventType, out eventHandler) ? eventHandler : null;
    }

以上是否应该将父类的handle一起加载？
