multimap::operator=

Replaces the elements of a multimap with a copy of another multimap.

multimap& operator=(
   const multimap& _Right
);
multimap& operator=(
   multimap&& _Right
);

Parameters

Remarks

After erasing any existing elements in a multimap, operator= either copies or moves the contents of _Right into the multimap.

Example

// multimap_operator_as.cpp
// compile with: /EHsc
#include <map>
#include <iostream>

int main( )
   {
   using namespace std;
   multimap<int, int> v1, v2, v3;
   multimap<int, int>::iterator iter;

   v1.insert(pair<int, int>(1, 10));

   cout << "v1 = " ;
   for (iter = v1.begin(); iter != v1.end(); iter++)
      cout << iter->second << " ";
   cout << endl;

   v2 = v1;
   cout << "v2 = ";
   for (iter = v2.begin(); iter != v2.end(); iter++)
      cout << iter->second << " ";
   cout << endl;

// move v1 into v2
   v2.clear();
   v2 = move(v1);
   cout << "v2 = ";
   for (iter = v2.begin(); iter != v2.end(); iter++)
      cout << iter->second << " ";
   cout << endl;
   }

Output

v1 = 10 
v2 = 10 
v2 = 10
