如果一个类型的默认成员被删除,那么这个声明的可访问性是什么呢？
class FooA {
public:
FooA() = delete;
FooA(FooA const&) = delete;
FooA& operator=(FooA const&) = delete;
}
class FooB {
private:
FooB() = delete;
FooB(FooB const&) = delete;
FooB& operator=(FooB const&) = delete;
}
class FooC {
protected:
FooC() = delete;
FooC(FooC const&) = delete;
FooC& operator=(FooC const&) = delete;
}
解决方法
虽然
accessibility and deletedness are orthogonal,很难看出在你提出的情况下如何有实际的区别.
