C# Класс Nexus.Client.Util.Antlr.AntlrLexerBase

The base lexer for ANTRL lexers.

This extends the generated lexer in order to make error handling sane, and to make the errors friendlier.

Наследование: Antlr.Runtime.Lexer

Открытые методы

Метод	Описание
AntlrLexerBase ( ) : System	The default constructor.
AntlrLexerBase ( ICharStream input, Antlr.Runtime.RecognizerSharedState state ) : System	A simple constructor.
DisplayRecognitionError ( String tokenNames, RecognitionException e ) : void	Logs the given error to the ErrorTracker.
GetErrorMessage ( RecognitionException e, string tokenNames ) : string	Generates a human-readable error message for the given error.
NextToken ( ) : IToken	This reads the next token from the input. If there is a lexing error, this method inserts an error token containing the bad input, and continues lexing.
ReportError ( RecognitionException e ) : void	Reports the given error. This ensures that the error is thrown so that our NextToken() override can handle it.

The default constructor.

public AntlrLexerBase ( ) : System
Результат	System

A simple constructor.

public AntlrLexerBase ( ICharStream input, Antlr.Runtime.RecognizerSharedState state ) : System
input	ICharStream	The code to lex.
state	Antlr.Runtime.RecognizerSharedState	The to use.
Результат	System

Logs the given error to the ErrorTracker.

public DisplayRecognitionError ( String tokenNames, RecognitionException e ) : void
tokenNames	String	The names of the tokens in the current language.
e	Antlr.Runtime.RecognitionException	The error.
Результат	void

Generates a human-readable error message for the given error.

public GetErrorMessage ( RecognitionException e, string tokenNames ) : string
e	Antlr.Runtime.RecognitionException	The error.
tokenNames	string	The names of the tokens in the current language.
Результат	string

This reads the next token from the input.

If there is a lexing error, this method inserts an error token containing the bad input, and continues lexing.

public NextToken ( ) : IToken
Результат	IToken

Reports the given error.

This ensures that the error is thrown so that our NextToken() override can handle it.

public ReportError ( RecognitionException e ) : void
e	Antlr.Runtime.RecognitionException	The error.
Результат	void
