模板类和继承问题-“列表”未命名非静态数据成员或基类

Question

I'm relatively new to c++ and having a very hard time figuring out the issue with what I am doing. I hope my description isn't too confusing, but I have two separate class hierarchies going on. The base for both are class templates.

Class hierarchy one is as follows

template <class T>
class Order {}

// StoreOrder inherits from Order
class StoreOrder: public Order<Item *> {}

Class hierarchy two is as follows. The tricky part here is in OrderList

template <class T>
class List{}

// OrderList inherits from List
class OrderList : public List<StoreOrder *>{}

OrderList::OrderList(): List(), DatabasePath(""){} 

When I pass a StoreOrder as the List template type I get an error in the constructor function that says

'List' does not name a non-static data member or base class

All classes work fine in every other situation that I've used them, so I believe it has to do with the fact that StoreOrder and OrderList both derive from template classes. Any help would be great.

Answer 1

Instead of:

OrderList::OrderList(): List(), DatabasePath(""){} 

Use:

OrderList::OrderList(): List<StoreOrder *>(), DatabasePath(""){} 

List is not a type. List<StoreOrder*> is a type.
