std::ostream_iterator<T,CharT,Traits>::operator=: std::ostream_iterator<T,CharT,Traits>::operator=

NAME

std::ostream_iterator<T,CharT,Traits>::operator= - std::ostream_iterator<T,CharT,Traits>::operator=

Synopsis

ostream_iterator& operator=( const T& value );

Inserts value into the associated stream, then inserts the delimiter, if one was specified at construction time.
If out_stream is a pointer to the associated std::basic_ostream and delim is the delimiter specified at the construction of this object, then the effect is equivalent to
*out_stream << value;
if(delim != 0)
*out_stream << delim;
return *this;

Parameters

value - the object to insert

Return value

*this

Notes

T can be any class with a user-defined operator<<

Example

// Run this code

  #include <iostream>
  #include <iterator>

  int main()
  {
      std::ostream_iterator<int> i1(std::cout, ", ");
      *i1++ = 1; // usual form, used by standard algorithms
      *++i1 = 2;
      i1 = 3; // neither * nor ++ are necessary
      std::ostream_iterator<double> i2(std::cout);
      i2 = 3.14;
  }

Output:

  1, 2, 3, 3.14
