Operating on strings using IO interface

Ruby
1

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
Thomas

lol, funny, on my kubuntu-box, ri runned until yesterday, and now:
ri StringIO

Sometimes I hate those automatic updates…
