is_member_function_pointer Class

Tests if type is a pointer to member function.

Syntax

template <classTy> structis_member_function_pointer;

Parameters

Ty
The type to query.

Remarks

An instance of the type predicate holds true if the type Ty is a pointer to member function or a cv-qualified pointer to member function, otherwise it holds false.

Example

// std__type_traits__is_member_function_pointer.cpp// compile with: /EHsc #include<type_traits> #include<iostream>structtrivial { int val; }; structfunctional { intf(); }; intmain() { std::cout << "is_member_function_pointer<trivial *> == " << std::boolalpha << std::is_member_function_pointer<trivial *>::value << std::endl; std::cout << "is_member_function_pointer<int trivial::*> == " << std::boolalpha << std::is_member_function_pointer<int trivial::*>::value << std::endl; std::cout << "is_member_function_pointer<int (functional::*)()> == " << std::boolalpha << std::is_member_function_pointer<int (functional::*)()>::value << std::endl; return (0); }

is_member_function_pointer<trivial *> == false is_member_function_pointer<int trivial::*> == false is_member_function_pointer<int (functional::*)()> == true
