Examples of org.antlr.v4.runtime.ANTLRInputStream

org.antlr.v4.runtime.atn.NotSetTransition
Vacuum all input from a {@link Reader}/ {@link InputStream} and then treat itlike a {@code char[]} buffer. Can also pass in a {@link String} or{@code char[]} to use.
If you need encoding, pass in stream/reader with correct encoding.

      for (String line : lines)
      {
        fileLines.append(line);
      }


      ANTLRInputStream source = new ANTLRInputStream(new ByteArrayInputStream(fileLines.toString().getBytes()));


      ScssLexer lexer = new ScssLexer(source);
      TokenStream stream = new BufferedTokenStream(lexer);
      ScssParser par = new ScssParser(stream);
      par.getInterpreter().setPredictionMode(PredictionMode.LL_EXACT_AMBIG_DETECTION);
