abstract input adapter interface
Produces a stream of std::char_traits<char>::int_type characters from a std::istream, a buffer, or some other input type. Accepts the return of exactly one non-EOF character for future input. The int_type characters returned consist of all valid char values as positive values (typically unsigned char), plus an EOF value outside that range, specified by the value of the function std::char_traits<char>::eof(). This value is typically -1, but could be any arbitrary value which is not a valid char value.
