public class NoOpTerminalVisitor extends GremlinAntlrToJava
This is the entry point for converting the Gremlin Antlr grammar into Java. It is bound to aGraph
instance as that instance may spawn specificTraversal
orTraversalSource
types. A new instance should be created for each parse execution. The same as parent visitorGremlinAntlrToJava
but returnsBytecode
instead of aTraversal
orGraphTraversalSource
, and uses an overridden terminal step visitor.
