## Constructor & Destructor Documentation

## istreambuf_iterator() [1/3]

template<typename _CharT , typename _Traits >

constexpr std::istreambuf_iterator< _CharT, _Traits >::istreambuf_iterator | ( |  | ) |

inline noexcept

Construct end of input stream iterator.

Definition at line 102 of file streambuf_iterator.h.

## istreambuf_iterator() [2/3]

template<typename _CharT , typename _Traits >

std::istreambuf_iterator< _CharT, _Traits >::istreambuf_iterator | ( | istream_type & | __s | ) |

inline noexcept

Construct start of input stream iterator.

Definition at line 112 of file streambuf_iterator.h.

## istreambuf_iterator() [3/3]

template<typename _CharT , typename _Traits >

std::istreambuf_iterator< _CharT, _Traits >::istreambuf_iterator | ( | streambuf_type * | __s | ) |

inline noexcept

Construct start of streambuf iterator.

Definition at line 116 of file streambuf_iterator.h.

## Member Function Documentation

## equal()

template<typename _CharT , typename _Traits >

bool std::istreambuf_iterator< _CharT, _Traits >::equal | ( | const istreambuf_iterator< _CharT, _Traits > & | __b | ) | const

inline

Return true both iterators are end or both are not end.

Definition at line 172 of file streambuf_iterator.h.

References std::basic_streambuf< _CharT, _Traits >::sgetc().

## operator*()

template<typename _CharT , typename _Traits >

char_type std::istreambuf_iterator< _CharT, _Traits >::operator* | ( |  | ) | const

inline

Return the current character pointed to by iterator. This returns streambuf.sgetc(). It cannot be assigned. NB: The result of operator*() on an end of stream is undefined.

Definition at line 123 of file streambuf_iterator.h.

## operator++() [1/2]

template<typename _CharT , typename _Traits >

istreambuf_iterator& std::istreambuf_iterator< _CharT, _Traits >::operator++ | ( |  | ) |

inline

Advance the iterator. Calls streambuf.sbumpc().

Definition at line 137 of file streambuf_iterator.h.

## operator++() [2/2]

template<typename _CharT , typename _Traits >

istreambuf_iterator std::istreambuf_iterator< _CharT, _Traits >::operator++ | ( | int |  | ) |

inline

Advance the iterator. Calls streambuf.sbumpc().
