Examples of org.renjin.parser.ParseState

org.renjin.parser.ParseState
ParseState contains the shared state of the Lexer and Parser.
These are values that were just simply all global in the C implementation.


  @Override
  public Token getTokenList(Segment text, int initialTokenType, int startOffset) {
   
    ParseOptions parseOptions = new ParseOptions();
    ParseState parseState = new ParseState();
    
    if(startOffset != text.getBeginIndex()) {
      System.out.println("startOffset = " + startOffset);
    }
