Re: Singleton a dedicnost

[mstevlik]

Nakoniec som to vyriesil takto, dufam ze je to spravne riesenie:

// predok KernelApp
public class KernelApp {
 private KernelApp app;  // interna premenna
 
 protected KernelApp() {   // konstruktor predka
 }
 
  protected static KernelApp createApp() {
    return null;  // tuto metodu prepisem v potomkovi
  }
 
 public static KernelApp getApp() {  // metoda kt. robi singleton
   if (app == null)
     app = new createApp();
   return app;
 }

}

// potomok MojaApp
public classMojaApp extends KernelApp {
 
 protected MojaApp() {  // konstruktor potomka
   super();
   // nejaka moja cinnost
 }
 
  protected static KernelApp createApp() {
    return new MojaApp();  // vratim si instanciu potomka
  }

}
