public MCErrorListener(MCParser parser)

Method Details

syntaxError

public void syntaxError(org.antlr.v4.runtime.Recognizer<?,?> recognizer,
 Object offendingSymbol,
 int line,
 int charPositionInLine,
 String msg,
 org.antlr.v4.runtime.RecognitionException e)

Specified by:

syntaxError in interface org.antlr.v4.runtime.ANTLRErrorListener

Overrides:

syntaxError in class org.antlr.v4.runtime.BaseErrorListener

extractNoKeywordTokens

protected static List<String> extractNoKeywordTokens(org.antlr.v4.runtime.Recognizer<?,?> recognizer,
 Set<Map.Entry<Integer,String>> epsilonRules)

containsRule

protected boolean containsRule(org.antlr.v4.runtime.misc.IntervalSet set,
 org.antlr.v4.runtime.Vocabulary vocabulary,
 String needle)

Parameters:

set - an IntervalSet of tokens

vocabulary - the token vocabulary

needle - the rule display name to search for

Returns:

Whether the interval set contains a rule with the display name of needle

getLineContext

public String getLineContext(org.antlr.v4.runtime.CharStream stream,
 int startIndex,
 int charPositionInLine)

getOffendingLine

protected String getOffendingLine(String entireInput,
 int tokenIndex)

Parameters:

entireInput - the entire input text

tokenIndex - the index of a token to find return its line

Returns:

the line

getExpectedRulesWithTokens

public boolean getExpectedRulesWithTokens(org.antlr.v4.runtime.atn.ATN atn,
 int stateNumber,
 org.antlr.v4.runtime.Vocabulary vocabulary,
 Map<Integer,Boolean> visitedStates,
 Set<Map.Entry<Integer,String>> expected)

Similiar to ATN.getExpectedTokens(int, RuleContext), but we also return the rule numbers

Parameters:

atn - the atn

stateNumber - the current state

vocabulary - Vocabulary

visitedStates - the already visited states

expected - a set of ruleIndex -to- expected token(s) entries

Returns:

whether an empty input is accepted
