Get the line number for the current position in the input stream. The
first line in the input is line 1.
getter/setter pairinherited

-
getter/setter pairinherited
-
modeNames
→ List<
String> -
final
- parseInfo → ParseInfo?
-
If profiling during the parse/lex, this will return DecisionInfo records
for each decision in recognizer in a ParseInfo object.

→ Map<
String, int> -
Get a map from rule names to rule indexes.

→ List<
String> -
final
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
-
serializedATN
→ List<
int> -
If this recognizer was generated, it will have a serialized ATN
representation of the grammar.
no setter
- sourceName → String
-
Gets the name of the underlying input source. This method returns a
non-null, non-empty string. If such a name is not known, this method
returns {@link IntStream#UNKNOWN_SOURCE_NAME}.
no setterinherited
- state ↔ int
-
getter/setter pairinherited
- text ↔ String
-
Return the text matched so far for the current token or any
text override.
getter/setter pairinherited
- token → Token?
-
Override if emitting multiple tokens.
no setterinherited
-
tokenFactory
↔ TokenFactory<
Token> -
getter/setter pairinherited
- tokenStartCharIndex ↔ int
-
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.
getter/setter pairinherited
- tokenStartCharPositionInLine ↔ int
-
The character position of first character within the line
getter/setter pairinherited
- tokenStartLine ↔ int
-
The line on which the first character of the token resides
getter/setter pairinherited
-
tokenTypeMap
→ Map<
String, int> -
Get a map from token names to token types.
no setterinherited
- type ↔ int
-
The token type for the current token
getter/setter pairinherited
- vocabulary → Vocabulary
-
Get the vocabulary used by the recognizer.
no setter
Methods
-
action(
RuleContext? _localctx, int ruleIndex, int actionIndex) → void -
inherited
-
addErrorListener(
ErrorListener listener) → void -
inherited
-
emit(
) → Token -
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.
inherited
-
emitEOF(
) → Token -
inherited
-
emitToken(
Token token) → void -
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).
inherited
-
getATN(
) → ATN -
Get the
ATNused by the recognizer for prediction. -
getCharErrorDisplay(
int c) → String -
inherited
-
getErrorDisplay(
String s) → String -
inherited
-
getErrorHeader(
RecognitionException< IntStream> e) → String -
What is the error header, normally line/character position information? */
inherited
-
getTokenType(
String tokenName) → int -
inherited
-
mode(
int m) → void -
inherited
-
more(
) → void -
inherited
-
nextToken(
) → Token -
Return a token from this source; i.e., match a token on the char stream.
inherited
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
notifyListeners(
LexerNoViableAltException e) → void -
inherited
-
popMode(
) → int -
inherited
-
precpred(
RuleContext? localctx, int precedence) → bool -
inherited
-
pushMode(
int m) → void -
inherited
-
recover(
RecognitionException< IntStream> re) → void -
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.
inherited
-
removeErrorListener(
ErrorListener listener) → void -
inherited
-
removeErrorListeners(
) → void -
inherited
-
reset(
[bool resetInput = false]) → void -
inherited
-
sempred(
RuleContext? _localctx, int ruleIndex, int actionIndex) → bool -
inherited
-
setToken(
Token _token) → void -
inherited
-
skip(
) → void -
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.
inherited
-
toString(
) → String -
A string representation of this object.
inherited
Operators
-
operator ==(
Object other) → bool -
The equality operator.
