ostream_iterator::operator*

Dereferencing operator used to implement the output iterator expression *ii = x.

ostream_iterator<Type, CharType, Traits>& operator*( );

Return Value

A reference to the ostream_iterator.

Remarks

The requirements for an output iterator that the ostream_iterator must satisfy require only the expression *ii = t be valid and says nothing about the operator or the operator= on their own. The member operator in this implementation returns *this.

Example

// ostream_iterator_op_deref.cpp
// compile with: /EHsc
#include <iterator>
#include <vector>
#include <iostream>

int main( )
{
   using namespace std;

   // ostream_iterator for stream cout
   // with new line delimiter
   ostream_iterator<int> intOut ( cout , "\n" );

   // Standard iterator interface for writing
   // elements to the output stream
   cout << "Elements written to output stream:" << endl;
   *intOut = 10;
   intOut++;      // No effect on iterator position
   *intOut = 20;
   *intOut = 30;
}
Elements written to output stream:
10
20
30
