Hi all,

I need to both parse incoming messages and generate outgoing messages in EDIFACT format (basically a structured delimited format).

I would like to have a Java model that will be generated by parsing a message. Then I would like to use the same model to create an instance and generate a message.

The first half is fine, I've used ANTLR before to go from raw -> Java objects. But I've never done the reverse, or if I have it's been custom.

Does ANTLR support generating using a grammar or is it really just a parse-only tool?
