public class InfluxDBSqlParserBaseVisitor<T>
extends org.antlr.v4.runtime.tree.AbstractParseTreeVisitor<T>
implements InfluxDBSqlParserVisitor<T>

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