org.apache.tinkerpop.gremlin.language.grammar.TraversalRootVisitor<G>

All Implemented Interfaces:

org.antlr.v4.runtime.tree.ParseTreeVisitor<Traversal>, GremlinVisitor<Traversal>

Direct Known Subclasses:

TraversalMethodVisitor

public class TraversalRootVisitor<G extends Traversal>
extends DefaultGremlinBaseVisitor<Traversal>

This visitor handles the cases when a new traversal is getting started. It could either be a nested traversal or a root traversal, but in either case should be anonymous.
