The type of an allocator for managing storage.

Example

 

// std_tr1__unordered_map__unordered_multimap_allocator_type.cpp 
// compile with: /EHsc 
#include <unordered_map> 
#include <iostream> 

typedef std::unordered_multimap<char, int> Mymap; 
typedef std::allocator<std::pair<const char, int> > Myalloc; 
int main() 
    { 
    Mymap c1; 

    Mymap::allocator_type al = c1.get_allocator(); 
    std::cout << "al == std::allocator() is " 
        << std::boolalpha << (al == Myalloc()) << std::endl; 

    return (0); 
    } 

al == std::allocator() is true
