Method Detail

getATN

public ATN getATN()

Description copied from class: Recognizer

Get the ATN used by the recognizer for prediction.

Specified by:

getATN in class Recognizer<java.lang.Integer,LexerATNSimulator>

Returns:

The ATN used by the recognizer for prediction.

getGrammarFileName

public java.lang.String getGrammarFileName()

Description copied from class: Recognizer

For debugging and other purposes, might want the grammar name. Have ANTLR generate an implementation for this method.

Specified by:

getGrammarFileName in class Recognizer<java.lang.Integer,LexerATNSimulator>

getTokenNames

@Deprecated
public java.lang.String[] getTokenNames()

Deprecated.

Description copied from class: Lexer

Used to print out token names like ID during debugging and error reporting. The generated parsers implement a method that overrides this to point to their String[] tokenNames.

Overrides:

getTokenNames in class Lexer

getRuleNames

public java.lang.String[] getRuleNames()

Specified by:

getRuleNames in class Recognizer<java.lang.Integer,LexerATNSimulator>

getChannelNames

public java.lang.String[] getChannelNames()

Overrides:

getChannelNames in class Lexer

getModeNames

public java.lang.String[] getModeNames()

Overrides:

getModeNames in class Lexer

getVocabulary

public Vocabulary getVocabulary()

Description copied from class: Recognizer

Get the vocabulary used by the recognizer.

Overrides:

getVocabulary in class Recognizer<java.lang.Integer,LexerATNSimulator>

Returns:

A Vocabulary instance providing information about the vocabulary used by the grammar.
