std::istreambuf_iterator< _Chstd::istreambuf3iterator< _CharT, _Traits >(3cxx)
NAME
std::istreambuf_iterator< _CharT, _Traits > - Provides input iterator
semantics for streambufs.
SYNOPSIS
Inherits std::iterator< input_iterator_tag, _CharT, _Traits::off_type,
_CharT *, _CharT >.
Public Types
typedef _Traits::off_type difference_type
Distance between iterators is represented as this type.
typedef input_iterator_tag iterator_category
One of the tag types.
typedef _CharT * pointer
This type represents a pointer-to-value_type.
typedef _CharT reference
This type represents a reference-to-value_type.
typedef _CharT value_type
The type 'pointed to' by the iterator.
typedef _CharT char_type

typedef _Traits traits_type

Public typedefs.
Public Member Functions
constexpr istreambuf_iterator () noexcept
Construct end of input stream iterator.
istreambuf_iterator (const istreambuf_iterator &) noexcept=default
istreambuf_iterator (istream_type &__s) noexcept
Construct start of input stream iterator.
istreambuf_iterator (streambuf_type *__s) noexcept
Construct start of streambuf iterator.
bool equal (const istreambuf_iterator &__b) const
Return true both iterators are end or both are not end.
char_type operator* () const
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.
istreambuf_iterator & operator++ ()
Advance the iterator. Calls streambuf.sbumpc().
istreambuf_iterator operator++ (int)
Advance the iterator. Calls streambuf.sbumpc().
istreambuf_iterator & operator= (const istreambuf_iterator &)
noexcept=default
