What's the Ruby equivalent for Java's StringReader?

Question

In Java, one can create an IO stream from a String like so:

Reader r = new StringReader("my text");

I'd like to be able to do the same in Ruby so I can take a string and treat it as an IO stream.

r = StringIO.new("my text")

One key thing that bit me (it's in the documentation; I just missed it) is that to get the result out you use #string, not #to_s. #to_s just tells you it's a StringIO. #string gives you the built result. – James A. Rosen Jun 09 '09 at 12:13
