Hi all: I am writing an app and could use a little advice from some of you oop gurus. A broad statement of the problem is this: I have an object that contains geometrical objects and need a way to write a description of those objects in different formats. Although not the exact case, you can consider this task similar to a drawing program where an object holds a list of drawing objects and it needs to be able to write these out in various formats, such as postscript or xfig. I know there are lots of ways to do this, including writing the objects out in a meta format and give all the other export classes the ability to parse the meta format. I am hoping someone has done something like this and has a clever way to do this in Ruby. A class pattern would be nice.
