如果它是一个子类, 也只能从满足上述条件并以Interface为后缀的类继承. 接口类不能被直接实例化, 因为它声明了纯虚函数. 为确保接口类的所有实现可被正确销毁, 必须为之声明虚析构函数 (作为上述第 1 条规则的特例, 析构函数不能是纯虚函数). 具体细节可参考 Stroustrup 的 The C++ Programming Language, 3rd...
One of the main ideas behind Golang is that it should be easy to learn and simple to use. Furthermore, developers should have no problem reading the language. Now, unlike C++, we understand that Go does not have a large feature set, which might be a problem for some. In its syntax,...
为确保接口类的所有实现可被正确销毁,必须为之声明虚析构函数(作为第1条规则的例外,析构函数不能是纯虚函数)。具体细节可参考Stroustrup的《The C++Programming Language, 3rd edition》第12.4节。 优点:以Interface为后缀可令他人知道不能为该接口类增加实现函数或非静态数据成员,这一点对于多重继承尤其重要。另外,...
