    • getOldValue

      public Object getOldValue()
      Description copied from interface: Notification
      Returns the value of the notifier's feature before the change occurred. For a list-based feature, this represents a value, or a list of values, removed from the list. For a move, this represents the old position of the moved value.
      Specified by:
      getOldValue in interface Notification
      Returns:
      the old value of the notifier's feature.

    • getNewValue

      public Object getNewValue()

    • isTouch

      public boolean isTouch()
      Description copied from interface: Notification
      Returns true if this notification represents an event that did not change the state of the notifying object. For the events Notification.ADD, Notification.ADD_MANY, Notification.REMOVE, Notification.REMOVE_MANY, Notification.MOVE, it always returns false. For the events Notification.RESOLVE and Notification.REMOVING_ADAPTER it always returns true. For the events Notification.SET and Notification.UNSET it returns true if the old and the new value are equal; In addition, for certain types of features there may be a distinction between being set to a default value and not being set at all, which implies that it has the default value. In this situation, even in the case that the old and new values are equal, isTouch may never the less return false in order to indicate that, although the value has not changed, the feature has gone from simply having a default value to being set to that same default value, or has gone from being set to the default value back to being unset.
      Specified by:
      isTouch in interface Notification
