public class NoOpTerminalVisitor
extends GremlinAntlrToJava

This is the entry point for converting the Gremlin Antlr grammar into Java. It is bound to a Graph instance as that instance may spawn specific Traversal or TraversalSource types. A new instance should be created for each parse execution. The same as parent visitor GremlinAntlrToJava but returns GremlinLang instead of a Traversal or GraphTraversalSource, and uses an overridden terminal step visitor.
