Detailed Description

  template<typename _Tp, typename _CharT = char, typename _Traits = char_traits<_CharT>>
class std::ostream_iterator< _Tp, _CharT, _Traits >"Provides output iterator semantics for streams. This class provides an iterator to write to an ostream. The type Tp is the only type written by this iterator and there must be an operator<<(Tp) defined.

Template Parameters
    _Tp The type to write to the ostream.
    _CharT The ostream char_type.
    _Traits The ostream char_traits.

  typedef output_iterator_tag std::iterator< output_iterator_tag , void , void , void , void >::iterator_category [inherited]

One of the tag types.

  typedef void std::iterator< output_iterator_tag , void , void , void , void >::pointer [inherited]

This type represents a pointer-to-value_type.

  typedef void std::iterator< output_iterator_tag , void , void , void , void >::reference [inherited]

This type represents a reference-to-value_type.

Constructor & Destructor Documentation

  template<typename _Tp , typename _CharT = char, typename _Traits = char_traits<_CharT>> std::ostream_iterator< _Tp, _CharT, _Traits >::ostream_iterator (ostream_type & __s) [inline], [noexcept]

Construct from an ostream.

  template<typename _Tp , typename _CharT = char, typename _Traits = char_traits<_CharT>> std::ostream_iterator< _Tp, _CharT, _Traits >::ostream_iterator (ostream_type & __s, const _CharT * __c) [inline], [noexcept]
Construct from an ostream.

The delimiter string c is written to the stream after every Tp written to the stream. The delimiter is not copied, and thus must not be destroyed while this iterator is in use.

Parameters
    __s Underlying ostream to write to.
    __c CharT delimiter string to insert.

  template<typename _Tp , typename _CharT = char, typename _Traits = char_traits<_CharT>> std::ostream_iterator< _Tp, _CharT, _Traits >::ostream_iterator (const ostream_iterator< _Tp, _CharT, _Traits > & __obj) [inline], [noexcept]

Copy constructor.

Member Function Documentation

  template<typename _Tp , typename _CharT = char, typename _Traits = char_traits<_CharT>> ostream_iterator & std::ostream_iterator< _Tp, _CharT, _Traits >::operator= (const _Tp & __value) [inline]

Writes value to underlying ostream using operator<<. If constructed with delimiter string, writes delimiter to ostream.
