public abstract class ModuleVisitor
extends Object

A visitor to visit a Java module. The methods of this class must be called in the following order: visitMainClass | ( visitPackage | visitRequire | visitExport | visitOpen | visitUse | visitProvide )* visitEnd. The methods visitRequire(String, int, String), visitExport(String, int, String...), visitOpen(String, int, String...) and visitPackage(String) take as parameter a package name or a module name. Unlike the other names which are internal names (names separated by slash), module and package names are qualified names (names separated by dot).
