tokenFactory_ TokenFactory!CommonToken tokenFactory_;: How to create token objects @uml @read @write @override
_token Token _token;: The goal of all lexer rules/methods is to create a token object. This is an instance variable as multiple rules may collaborate to create a single token. nextToken will return this object after matching lexer rule(s). If you subclass to allow multiple token emissions, then set this to the last token to be matched or something nonnull so that the auto token emit mechanism will not emit another token.
_modeStack IntegerStack _modeStack;: Undocumented in source.
_tokenStartCharIndex int _tokenStartCharIndex;: What character index in the stream did the current token start at? Needed, for example, to get the text for current token. Set at the start of nextToken.
_tokenStartLine int _tokenStartLine;: The line on which the first character of the token resides
_tokenStartCharPositionInLine int _tokenStartCharPositionInLine;: The character position of first character within the line
_hitEOF bool _hitEOF;: Undocumented in source.
_channel int _channel;: The channel number for the current token
_type int _type;: The token type for the current token
_mode int _mode;: Undocumented in source.
_text Variant _text;: You can set the text for the current token to override what is in the input char buffer. Use setText() or can set this instance var.
reset void reset(): Undocumented in source. Be warned that the author may not have intended to support it.
nextToken Token nextToken(): Return a token from this source; i.e., match a token on the char stream.
skip void skip(): Instruct the lexer to skip creating a token for current lexer rule and look for another token. nextToken() knows to keep looking when a lexer rule finishes with token set to SKIP_TOKEN. Recall that if token==null at end of any token rule, it creates one for you and emits it.
more void more(): Undocumented in source. Be warned that the author may not have intended to support it.
mode void mode(int m): Undocumented in source. Be warned that the author may not have intended to support it.
pushMode void pushMode(int m): Undocumented in source. Be warned that the author may not have intended to support it.
popMode int popMode(): Undocumented in source. Be warned that the author may not have intended to support it.
setInputStream void setInputStream(IntStream input): Set the char stream and reset the lexer @uml @override
getSourceName string getSourceName(): Undocumented in source. Be warned that the author may not have intended to support it.
getInputStream CharStream getInputStream(): @uml @override
emit void emit(Token token): By default does not support multiple emits per nextToken invocation for efficiency reasons. Subclass and override this method, nextToken, and getToken (to push tokens into a list and pull from that list rather than a single variable as this implementation does).
emit Token emit(): The standard method called to automatically emit a token at the outermost lexical rule. The token object should point into the char buffer start..stop. If there is a text override in 'text', use that to set the token's text. Override this method to emit custom Token objects or provide a new factory.
emitEOF Token emitEOF(): Undocumented in source. Be warned that the author may not have intended to support it.
getLine int getLine(): Undocumented in source. Be warned that the author may not have intended to support it.
getCharPositionInLine int getCharPositionInLine(): Undocumented in source. Be warned that the author may not have intended to support it.
setLine void setLine(int line): Undocumented in source. Be warned that the author may not have intended to support it.
setCharPositionInLine void setCharPositionInLine(int charPositionInLine): Undocumented in source. Be warned that the author may not have intended to support it.
getCharIndex int getCharIndex(): What is the index of the current character of lookahead?
getText Variant getText(): Return the text matched so far for the current token or any text override.
setText void setText(Variant text): Set the complete text of this token; it wipes any previous changes to the text.
getToken Token getToken(): Override if emitting multiple tokens.
setToken void setToken(Token token): Undocumented in source. Be warned that the author may not have intended to support it.
setType void setType(int ttype): Undocumented in source. Be warned that the author may not have intended to support it.
getType int getType(): Undocumented in source. Be warned that the author may not have intended to support it.
setChannel void setChannel(int channel): Undocumented in source. Be warned that the author may not have intended to support it.
getChannel int getChannel(): Undocumented in source. Be warned that the author may not have intended to support it.
getChannelNames string[] getChannelNames(): Undocumented in source. Be warned that the author may not have intended to support it.
getModeNames string[] getModeNames(): Undocumented in source. Be warned that the author may not have intended to support it.
getTokenNames string[] getTokenNames(): 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 @uml @override
getAllTokens Token[] getAllTokens(): Return a list of all Token objects in input char stream. Forces load of all tokens. Does not include EOF token.
recover void recover(LexerNoViableAltException e): Undocumented in source. Be warned that the author may not have intended to support it.
notifyListeners void notifyListeners(LexerNoViableAltException e): Undocumented in source. Be warned that the author may not have intended to support it.
getErrorDisplay string getErrorDisplay(string s): Undocumented in source. Be warned that the author may not have intended to support it.
getErrorDisplay string getErrorDisplay(int c): Undocumented in source. Be warned that the author may not have intended to support it.
getCharErrorDisplay string getCharErrorDisplay(int c): Undocumented in source. Be warned that the author may not have intended to support it.
recover void recover(RecognitionException re): Lexers can normally match any char in it's vocabulary after matching a token, so do the easy thing and just kill a character and hope it all works out. You can instead use the rule invocation stack to do sophisticated error recovery if you are in a fragment rule.
action void action(InterfaceRuleContext interfaceRuleContext, int ruleIndex, int actionIndex): @uml @override
tokenFactory TokenFactory!CommonToken tokenFactory(): Undocumented in source. Be warned that the author may not have intended to support it.
