is_member_pointer

template <class T>
struct is_member_pointer : public true_type-or-false_type {};

Inherits: If T is a (possibly cv-qualified) pointer to a member (either a function or 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_pointer.hpp> or #include <boost/type_traits.hpp>

Examples:

is_member_pointer<int (MyClass::*)> inherits from true_type.

is_member_pointer<int (MyClass::*)(char)>::type is the type true_type.

is_member_pointer<int (MyClass::*)(void)const>::value is an integral constant expression that evaluates to true.

is_member_pointer<T>::value_type is the type bool.
