## Public Types

typedef input_iterator_tag | iterator_category
| One of the tag types.
typedef CharT | value_type
| The type "pointed to" by the iterator.
typedef Traits::off_type | difference_type
| Distance between iterators is represented as this type.
typedef CharT * | pointer
| This type represents a pointer-to-value_type.
typedef CharT & | reference
| This type represents a reference-to-value_type.
typedef CharT | char_type
| Public typedefs.
typedef Traits | traits_type
| Public typedefs.
typedef Traits::int_type | int_type
| Public typedefs.
typedef basic_streambuf< CharT, Traits > | streambuf_type

## Public Member Functions

| istreambuf_iterator () throw ()
| Construct end of input stream iterator.
| istreambuf_iterator (istream_type &s) throw ()
| Construct start of input stream iterator.
| istreambuf_iterator (streambuf_type *s) throw ()
| Construct start of streambuf iterator.
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().
bool | equal (const istreambuf_iterator &__b) const
| Return true both iterators are end or both are not end.
