Constructor & Destructor Documentation

◆ istreambuf_iterator() [1/3]

template<typename _CharT , typename _Traits >
constexpr std::istreambuf_iterator< _CharT, _Traits >::istreambuf_iterator ( )
inlinenoexcept

Construct end of input stream iterator.

Definition at line 107 of file streambuf_iterator.h.

◆ istreambuf_iterator() [2/3]

template<typename _CharT , typename _Traits >
std::istreambuf_iterator< _CharT, _Traits >::istreambuf_iterator ( istream_type &  __s)
inlinenoexcept

Construct start of input stream iterator.

Definition at line 117 of file streambuf_iterator.h.

◆ istreambuf_iterator() [3/3]

template<typename _CharT , typename _Traits >
std::istreambuf_iterator< _CharT, _Traits >::istreambuf_iterator ( streambuf_type *  __s)
inlinenoexcept

Construct start of streambuf iterator.

Definition at line 121 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 181 of file streambuf_iterator.h.

◆ 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 133 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 149 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().

Definition at line 163 of file streambuf_iterator.h.
