hash_set::operator=
Replaces the elements of the hash_set with a copy of another hash_set.
hash_set& operator=(
const hash_set& _Right
);
hash_set& operator=(
hash_set&& _Right
);
Parameters
Parameter |
Description |
_Right |
The hash_set Class being copied into the hash_set. |
Remarks
After erasing any existing elements in a hash_set, operator= either copies or moves the contents of _Right into the hash_set.
Example
// hash_set_operator_as.cpp
// compile with: /EHsc
#include <hash_set>
#include <iostream>
int main( )
{
using namespace std;
using namespace stdext;
hash_set<int> v1, v2, v3;
hash_set<int>::iterator iter;
v1.insert(10);
cout << "v1 = " ;
for (iter = v1.begin(); iter != v1.end(); iter++)
cout << iter << " ";
cout << endl;
v2 = v1;
cout << "v2 = ";
for (iter = v2.begin(); iter != v2.end(); iter++)
cout << iter << " ";
cout << endl;
// move v1 into v2
v2.clear();
v2 = move(v1);
cout << "v2 = ";
for (iter = v2.begin(); iter != v2.end(); iter++)
cout << iter << " ";
cout << endl;
}
Output
v1 = 10
v2 = 10
v2 = 10
