front_insert_iterator::operator=
Appends (pushes) a value onto the front of the container.
front_insert_iterator<Container>& operator=(
typename Container::const_reference _Val
);
front_insert_iterator<Container>& operator=(
typename Container::value_type&& _Val
);
Parameters
- _Val
The value to be assigned to the container.
Return Value
A reference to the last element inserted at the front of the container.
Remarks
The first member operator evaluates container.push_front(_Val), then returns *this.
The second member operator evaluates
container->push_front((typename Container::value_type&&)_Val),
then returns *this.
Example
// front_insert_iterator_op_assign.cpp
// compile with: /EHsc
#include <iterator>
#include <list>
#include <iostream>
int main( )
{
using namespace std;
list<int> L1;
front_insert_iterator<list<int> > iter ( L1 );
*iter = 10;
iter++;
*iter = 20;
iter++;
*iter = 30;
iter++;
list <int>::iterator vIter;
cout << "The list L1 is: ( ";
for ( vIter = L1.begin ( ) ; vIter != L1.end ( ); vIter++ )
cout << *vIter << " ";
cout << ")." << endl;
}
The list L1 is: ( 30 20 10 ).
