[erlang-questions] how: string stream?

[YC]

Hi all -

are there something equivalent to a string stream in Erlang?  The io module
utilizes a IoDevice(), but it seems an IoDevice is either a file or socket,
and unclear how to extend it.

I'm also wondering how to implement the equivalent of chaining streams
together to perform layers of processing - any examples are appreciated.

Thanks,
yc
