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.
Compiler Compatibility: All current compilers are supported by this trait.
Header: #include
<boost/type_traits/is_member_pointer.hpp>
or #include <boost/type_traits.hpp>
Examples:
is_member_pointer<int (MyClass::*)>inherits fromtrue_type.
is_member_pointer<int (MyClass::*)(char)>::typeis the typetrue_type.
is_member_pointer<int (MyClass::*)(void)const>::valueis an integral constant expression that evaluates to true.
is_member_pointer<T>::value_typeis the typebool.
