Is there a std::noncopyable (or equivalent)?
No, because there is a standard way to make a class non-copyable:
class MyClass
{
MyClass(const MyClass&) = delete;
MyClass& operator=(const MyClass&) = delete;
}:
A class that is non-copyable can however be made movable by overloading a constructor from MyClass&&
.
The declaration to make the class non-copyable (above) can be in the public or private section.
If you don't really want to type all that out every time, you can always define a macro something like:
#define NONCOPYABLE(Type) Type(const Type&)=delete; Type& operator=(const Type&)=delete
class MyClass
{
NONCOPYABLE(MyClass);
// etc.
};
I'm sure you already figured it out by reading CashCow's post, but I thought I might as well provide a base class for noncopyable classes.
class Noncopyable {
public:
Noncopyable() = default;
~Noncopyable() = default;
private:
Noncopyable(const Noncopyable&) = delete;
Noncopyable& operator=(const Noncopyable&) = delete;
};
