    • Method Detail

      • addListener

        vjavax.observer.Subscription addListener​(ChangeListener l)
        Adds the specified change listener. Listeners will be notified about changes regardless of whether change recording is enabled. This allows to react to and/or undo specific changes without the overhead of storing all previous events in a collection. The listener registers with all objects of the current object graph.
        Parameters:
        l - the listener to add
        Returns:
        a subscription which allows to unsubscribe the specified listener

      • addListener

        Adds the specified change listener. Listeners will be notified about changes regardless of whether change recording is enabled. This allows to react to and/or undo specific changes without the overhead of storing all previous events in a collection. Optionally the listener registers with all objects of the current object graph.
        Parameters:
        l - the listher to add
        recursive - determines whether to add the listener recuirsively to all objects of the current object graph
        Returns:
