class TypeA
{
public TypeA Copy () { ... }
public bool IsEqual(TypeA mytypeA) { ... }
public bool IsSame(TypeA mytypeA) { ... }
...
}
class TypeACollection : List<TypeA>
{
public bool IsSame (TypeACollection typeAs)
{
if (Count != typeAs.Count)
return false;
return this[0].IsSame(typeAs[0]);
}
...
}
TypeB、TypeC 具有与 TypeA 类似的 Copy/IsEqual/IsSame 功能。TypeBCollection、TypeACollection 有类似的 IsSame。例外是 TypeBCollection 使用 TypeB.IsSame,TypeCCollection 使用 TypeC.IsSame。
现在,我计划添加 2 个新类:LocData 和 LocDataCollection
class LocData
{
public virtual TypeA Copy () { ... }
public virtual bool IsEqual(TypeA mytypeA) { ... }
public virtual bool IsSame(TypeA mytypeA) { ... }
...
}
class LocDataCollection<T> : List<LocData> where T: LocData
{
public bool IsSame (LocDataCollection<T> typeAs)
{
if (Count != typeAs.Count)
return false;
return this[0].IsSame(typeAs[0]);
}
...
}
并重写现有代码,
class TypeA : LocData
{
public new TypeA Copy () { ... }
public new bool IsEqual(TypeA mytypeA) { ... }
public new bool IsSame(TypeA mytypeA) { ... }
...
}
class TypeACollection : ???
{
???
// so I can remove IsSame here,
// when I call IsSame, it will use one from LocDataCollection and still call
// TypeA.IsSame
...
}
现在我迷失在抽象/虚拟/通用/...,这是最好的方法?
