has_trivial_copy_constructor Class
Tests if type has a trivial copy constructor.
template<class Ty>
struct has_trivial_copy_constructor;
Parameters
- Ty
The type to query.
Remarks
An instance of the type predicate holds true if the type Ty is a class that has only trivial copy constructors, otherwise it holds false.
A copy constructor for a class Ty is trivial if:
it is implicitly declared
the class Ty has no virtual functions
the class Ty has no virtual bases
all the direct bases of the class Ty have trivial copy constructors
the classes of all the non-static data members of class type have trivial copy constructors
the classes of all the non-static data members of type array of class have trivial copy constructors
