If T is a polymorphic class (that is, a class that declares or inherits at least one virtual function), provides the member constant value equal Template:cpp. For any other type, value is Template:cpp.

Inherited from std::integral_constant

Member constants

value [static]

true if T is a polymorphic class type , false otherwise (public static member constant)

Member functions

operator bool	converts the object to bool, returns value (public member function)
operator() (C++14)	returns value (public member function)

Member types

Type	Definition
value_type	bool
type	std::integral_constant<bool, value>

Notes

Only polymorphic classes contain hidden RTTI information which makes it possible to examine and convert them with dynamic_cast.
