Class IdentifierParserBaseVisitor<T>

java.lang.Object

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

org.apache.iotdb.db.qp.sql.IdentifierParserBaseVisitor<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>, IdentifierParserVisitor<T>

public class IdentifierParserBaseVisitor<T>
extends org.antlr.v4.runtime.tree.AbstractParseTreeVisitor<T>
implements IdentifierParserVisitor<T>

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

Constructor Details

IdentifierParserBaseVisitor

public IdentifierParserBaseVisitor()

Method Details

visitIdentifier

public T visitIdentifier(IdentifierParser.IdentifierContext ctx)

Visit a parse tree produced by IdentifierParser.identifier().

The default implementation returns the result of calling AbstractParseTreeVisitor.visitChildren(org.antlr.v4.runtime.tree.RuleNode) on ctx.

Specified by:

visitIdentifier in interface IdentifierParserVisitor<T>

Parameters:

ctx - the parse tree

Returns:

the visitor result

visitKeyWords

public T visitKeyWords(IdentifierParser.KeyWordsContext ctx)

Visit a parse tree produced by IdentifierParser.keyWords().

The default implementation returns the result of calling AbstractParseTreeVisitor.visitChildren(org.antlr.v4.runtime.tree.RuleNode) on ctx.

Specified by:

visitKeyWords in interface IdentifierParserVisitor<T>

Parameters:

ctx - the parse tree

Returns:

the visitor result
