Operating on strings using IO interface

ruby-talk

Hello,

is there a means that a piece of software can use just the IO
interface transparently without needing to know, whether the data to
read (resp. to write) is coming from (resp. going to) a file or a
string? Something comparable to stringstream in C++?

Regards
