deque::get_allocator

public member function
allocator_type get_allocator() const;

Get allocator

Returns the allocator object used to constuct the deque object.

Parameters

none

Return Value

The allocator.

Member type allocator_type is defined to the same as the second template parameter used to instantitate this specific deque class (its Allocator type).

// deque::get_allocator
#include <iostream>
#include <deque>
using namespace std;
int main ()
{
  deque<int> mydeque;
  int * p;
  unsigned int i;
  // allocate an array of 5 elements using deque's allocator:
  p=mydeque.get_allocator().allocate(5);
  // assign some values to array
  for (i=0; i<5; i++) p[i]=i;
  cout << "The allocated array contains:";
  for (i=0; i<5; i++) cout << " " << p[i];
  cout << endl;
  mydeque.get_allocator().deallocate(p,5);
  return 0;
}

The example shows an elaborate way to allocate memory for an array of ints using the same allocator used by the deque object. Output:
The allocated array contains: 0 1 2 3 4

Complexity

Constant.
