	(1)
istreambuf_iterator() throw();			(until C++11)
constexpr istreambuf_iterator() noexcept;			(since C++11)
istreambuf_iterator( std::basic_istream<CharT,Traits>& is ) noexcept;		(2)

1) Constructs an end-of-stream iterator.

2) Initializes the iterator and stores the value of is.rdbuf() in a data member. If is.rdbuf() is null, then end-of-stream iterator is constructed.

3) Initializes the iterator and stores the value of s in a data member. If s is null, then end-of-stream iterator is constructed.

4) Effectively call (3) with the streambuf_type* pointer p holds.

5) The copy constructor is explicitly defaulted.

Parameters

is	-	stream to obtain the stream buffer from
s	-	stream buffer to initialize the iterator with
p	-	object with implementation defined proxy type
