      Modifier and Type Method Description
      static double getDistance​(PamelaModelFactory factory, java.lang.Object o1, java.lang.Object o2)
      Compute the distance (double value between 0.0 and 1.0) between this object and an opposite object (which must be of right type!) If two objects are equals, return 0.
      static <I> double getDistance​(ProxyMethodHandler<I> source, java.lang.Object obj)
      Compute the distance (double value between 0.0 and 1.0) between this object and an opposite object (which must be of right type!) If two objects are equals, return 0.
      protected static boolean isEqual​(java.lang.Object oldValue, java.lang.Object newValue)  
      static <I> boolean updateWith​(ProxyMethodHandler<I> source, I obj)
      Called to update source object while comparing it to opposite object, (which must be of right type!), examining each property values.
      Collections are handled while trying to match updated objects with a given strategy
      Perform required changes on this object so that at the end of the call, equalsObject(object) shoud return true
      Also perform required notifications, so that it is safe to call that method in a deployed environment
