Constructor Details

XPathLexer

public XPathLexer(CharStream input)

Method Details

getGrammarFileName

public 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<Integer,LexerATNSimulator>

getRuleNames

public String[] getRuleNames()

Specified by:

getRuleNames in class Recognizer<Integer,LexerATNSimulator>

getModeNames

public String[] getModeNames()

Overrides:

getModeNames in class Lexer

getTokenNames

@Deprecated
public 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

getVocabulary

public Vocabulary getVocabulary()

Description copied from class: Recognizer

Get the vocabulary used by the recognizer.

Overrides:

getVocabulary in class Recognizer<Integer,LexerATNSimulator>

Returns:

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

getATN

public ATN getATN()

Description copied from class: Recognizer

Get the ATN used by the recognizer for prediction.

Specified by:

getATN in class Recognizer<Integer,LexerATNSimulator>

Returns:

The ATN used by the recognizer for prediction.

nextToken

public Token nextToken()

Description copied from class: Lexer

Return a token from this source; i.e., match a token on the char stream.

Specified by:

nextToken in interface TokenSource

Overrides:

nextToken in class Lexer

consume

public void consume()

getCharPositionInLine

public int getCharPositionInLine()

Description copied from interface: TokenSource

Get the index into the current line for the current position in the input stream. The first character on a line has position 0.

Specified by:

getCharPositionInLine in interface TokenSource

Overrides:

getCharPositionInLine in class Lexer

Returns:

The line number for the current position in the input stream, or -1 if the current token source does not track character positions.

matchID

public String matchID()

matchString

public String matchString()

isNameChar

public boolean isNameChar(int c)

isNameStartChar

public boolean isNameStartChar(int c)
