NAME¶
std::istreambuf_iterator< _CharT, _Traits > - Provides input iterator semantics for streambufs.
SYNOPSIS¶
#include <streambuf_iterator.h>
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(). istreambuf_iterator
