Method Detail


public void operate(Score score,
                    SelectionBuffer selectionBuffer)
Implement this method to do whatever you want to the Vector of Note accessible at selectionBuffer
       // transpose pitch up or down by adding a variable called "interval" to its pitch
       public void operate(SelectionBuffer selectionBuffer) {
        for (Enumeration e=selectionBuffer.elements(); e.hasMoreElements(); ) {
                Note note = (Note)e.nextElement();
                if (!note.isRest()) {
                        // get pitch data, transpose it, and set it again
                        // Use NoteFactory to recalculate staff level, accidental, and stem direction
                        NoteFactory.setLevelPitch(note, note.getPitchData());
