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
