1,2) Constructs an end-of-stream iterator.
3) 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.
4) Initializes the iterator and stores the value of s in a data member. If s is null, then end-of-stream iterator is constructed.
5) Effectively call (3) with the streambuf_type* pointer p holds.
6) The copy constructor is trivial and explicitly defaulted.

The copy constructor is effectively implicitly declared and not guaranteed to be trivial.

Parameters

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