 o addHighlight
 public abstract Object addHighlight(int p0,
                                     int p1,
                                     Highlighter. HighlightPainter p) throws BadLocationException
Adds a highlight to the view. Returns a tag that can be used to refer to the highlight.

an object that refers to the highlight

                                      int p1) throws BadLocationException
