makeRuleNames

makeLiteralNames

private static String[] makeLiteralNames()

makeSymbolicNames

private static String[] makeSymbolicNames()

getTokenNames

@Deprecated
public String[] getTokenNames()

Deprecated.

Description copied from class: Recognizer

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.

Specified by:

getTokenNames in class Recognizer<Token,ParserATNSimulator>

getVocabulary

@NotNull
public Vocabulary getVocabulary()

Description copied from class: Recognizer

Get the vocabulary used by the recognizer.

Overrides:

getVocabulary in class Recognizer<Token,ParserATNSimulator>

Returns:

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

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<Token,ParserATNSimulator>

getRuleNames

public String[] getRuleNames()

Specified by:

getRuleNames in class Recognizer<Token,ParserATNSimulator>

getSerializedATN

public String getSerializedATN()

Description copied from class: Recognizer

If this recognizer was generated, it will have a serialized ATN representation of the grammar.

For interpreters, we don't know their serialized ATN despite having created the interpreter from it.

Overrides:

getSerializedATN in class Recognizer<Token,ParserATNSimulator>

createFailedPredicateException

@NotNull
private FailedPredicateException createFailedPredicateException()

createFailedPredicateException

@NotNull
private FailedPredicateException createFailedPredicateException(@Nullable
 String predicate)

createFailedPredicateException

@NotNull
protected FailedPredicateException createFailedPredicateException(@Nullable
 String predicate,
 @Nullable
 String message)

_adaptivePredict

private int _adaptivePredict(int decision)

Hot-path helper used by generated rule methods. Prefer this over fetching the interpreter via the public accessor so the field is loaded once and the call site stays monomorphic for the JIT. Named with a leading underscore to avoid colliding with a user rule named adaptivePredict.

Uses _interp directly (same storage as Recognizer.getInterpreter()/Recognizer.setInterpreter(ATNInterpreter)). Callers that replace the simulator must use setInterpreter; overriding only getInterpreter() without updating the field is unsupported for generated decision sites (and for much of the runtime already).

_sync

private void _sync()

Hot-path helper used by generated rule methods so every decision site shares one monomorphic call to the error strategy. Named with a leading underscore to avoid colliding with a user rule named sync.

Skips the virtual sync call when the installed strategy reports isSyncRequired() is false (two-stage SLL / BailErrorStrategy).

_match

private Token _match(int ttype)

Monomorphic match used by generated token sites. Public Parser.match(int) remains for handwritten callers and subclasses. reportMatchRequired is false for DefaultErrorStrategy, so the success path is a field check. A custom strategy that returns true from ANTLRErrorStrategy.isReportMatchRequired() is notified on every successful match.

_prec

private boolean _prec(int p)

Monomorphic precedence test for left-recursive operator alts. Equivalent to Parser.precpred(org.antlr.v4.runtime.RuleContext, int) without a virtual call or unused context.

                                                               throws RecognitionException

Throws:

RecognitionException

public final graphemesParser.GraphemesContext graphemes()
                                                 throws RecognitionException

Throws:
