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.

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().
