How do you extend your grammar ?

Just came across this when I was building a simple code transformer. You mean you build a Antlr ParseTree Neo4J graph and store it in the DB ? How does it help you refactor ? I am using Antlr code itself to refactor.

Does this build inmemory without an actual Neo4J DB ? If so then just visualizing the nodes is going to be very powerful.
