Usage

From source file:excecoes.SyntaxError.java

public SyntaxError(String message, RecognitionException e, int line, int charPositionInLine) {
    super(message, e.getRecognizer(), e.getInputStream(), (ParserRuleContext) e.getCtx());
    this.setOffendingToken(e.getOffendingToken());
    this.initCause(e);
    this.setLine(line);
    this.setCharPositionInLine(charPositionInLine);
