template <class T>
struct is_member_object_pointer : public true_type-or-false_type {};
Inherits: If T is a (possibly cv-qualified) pointer to a member object (a data member) then inherits from true_type, otherwise inherits from false_type.
C++ Standard Reference: 3.9.2 and 8.3.3.
Header: #include
<boost/type_traits/is_member_object_pointer.hpp>
or #include <boost/type_traits.hpp>
Examples:
is_member_object_pointer<int (MyClass::*)>inherits fromtrue_type.
is_member_object_pointer<double (MyClass::*)>::typeis the typetrue_type.
is_member_object_pointer<const int (MyClass::*)>::valueis an integral constant expression that evaluates to true.
is_member_object_pointer<int (MyClass::*)(void)>::valueis an integral constant expression that evaluates to false: the argument in this case is a pointer to a member function and not a member object, see is_member_function_pointer and is_member_pointer
is_member_object_pointer<T>::value_typeis the typebool.
