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());
