com.google.dart.engine.scanner.IncrementalScanner.rescan()

Given the stream of tokens scanned from the original source, the modified source (the result of replacing one contiguous range of characters with another string of characters), and a specification of the modification that was made, return a stream of tokens scanned from the modified source. The original stream of tokens will not be modified. @param originalStream the stream of tokens scanned from the original source @param index the index of the first character in both the original and modified source that wasaffected by the modification @param removedLength the number of characters removed from the original source @param insertedLength the number of characters added to the modified source


    // Produce an updated token stream
    CharacterReader reader = new CharSequenceReader(cache.getNewContents());
    BooleanErrorListener errorListener = new BooleanErrorListener();
    IncrementalScanner scanner = new IncrementalScanner(cache.getSource(), reader, errorListener);
    scanner.rescan(
        cache.getResolvedUnit().getBeginToken(),
        cache.getOffset(),
        cache.getOldLength(),
        cache.getNewLength());
    if (errorListener.getErrorReported()) {
