Package org.apache.iotdb.db.qp.sql

Class PathParserBaseVisitor<T>

java.lang.Object

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

org.apache.iotdb.db.qp.sql.PathParserBaseVisitor<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>, PathParserVisitor<T>

public class PathParserBaseVisitor<T>
extends org.antlr.v4.runtime.tree.AbstractParseTreeVisitor<T>
implements PathParserVisitor<T>

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

PathParserBaseVisitor

public PathParserBaseVisitor()

Method Detail

visitPath

public T visitPath(PathParser.PathContext ctx)

Visit a parse tree produced by PathParser.path().

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

Specified by:

visitPath in interface PathParserVisitor<T>

Parameters:

ctx - the parse tree

Returns:

the visitor result

visitPrefixPath

public T visitPrefixPath(PathParser.PrefixPathContext ctx)

Visit a parse tree produced by PathParser.prefixPath().

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

Specified by:

visitPrefixPath in interface PathParserVisitor<T>

Parameters:

ctx - the parse tree

Returns:

the visitor result

visitSuffixPath

public T visitSuffixPath(PathParser.SuffixPathContext ctx)

Visit a parse tree produced by PathParser.suffixPath().

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

Specified by:

visitSuffixPath in interface PathParserVisitor<T>

Parameters:

ctx - the parse tree

Returns:

the visitor result

visitNodeName

public T visitNodeName(PathParser.NodeNameContext ctx)

Visit a parse tree produced by PathParser.nodeName().

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

Specified by:

visitNodeName in interface PathParserVisitor<T>

Parameters:

ctx - the parse tree

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

Specified by:

visitWildcard in interface PathParserVisitor<T>

Parameters:

ctx - the parse tree

Returns:

the visitor result

visitIdentifier

public T visitIdentifier(PathParser.IdentifierContext ctx)

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

Specified by:

visitIdentifier in interface PathParserVisitor<T>

Parameters:

ctx - the parse tree

Returns:

the visitor result

visitKeyWords

public T visitKeyWords(PathParser.KeyWordsContext ctx)
