Class VisitorsGenerator

java.lang.Object

EDU.purdue.jtb.generate.VisitorsGenerator

public class VisitorsGenerator
extends Object

Class VisitorsGenerator contains methods to generate: CODEJAVA

• the different IXxxVisitor interfaces and DepthFirstXxxVisitor classes files,
• the signature files.

Class maintains a state, and is not supposed to be run in parallel threads (on the same grammar). It does not generate the files in parallel.

TODO add test runs on generated default visitors
