Class GQLBaseVisitor<T>

java.lang.Object

org.antlr.v4.runtime.tree.AbstractParseTreeVisitor<T>

org.apache.tinkerpop.gremlin.gql.GQLBaseVisitor<T>

Type Parameters:

T - The return type of the visit operation. Use Void for operations with no return type.

All Implemented Interfaces:

org.antlr.v4.runtime.tree.ParseTreeVisitor<T>, GQLVisitor<T>

public class GQLBaseVisitor<T>
extends org.antlr.v4.runtime.tree.AbstractParseTreeVisitor<T>
implements GQLVisitor<T>

This class provides an empty implementation of GQLVisitor, which can be extended to create a visitor which only needs to handle a subset of the available methods.
