The MediaPlayer property is exposed as a ReadOnlyObjectProperty inasmuch as we don't want users of the class
to be able to set the MediaPlayer instance to a new value. Now that we have a nicely encapsulated class for our media,
we turn our attention to separating our UI code into more manageable chunks, or views . A new AbstractView base
class is created to eliminate duplication by holding some code that is common to all of our views. This small class is
shown in Listing 9-11.
Listing 9-11. The AbstractView Base Class
public abstract class AbstractView {
protected final SongModel songModel;
protected final Node viewNode;
public AbstractView(SongModel songModel) {
this.songModel = songModel;
this.viewNode = initView();
}
public Node getViewNode() {
return viewNode;
}
protected abstract Node initView();
}
