std::ostream_iterator::operator=(3) C++ Standard Libary std::ostream_iterator::operator=(3)

NAME

std::ostream_iterator::operator= - std::ostream_iterator::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
