    • Method Detail

      • setRelatedSubject

        void setRelatedSubject​(java.lang.Object listener,
                               java.lang.Object relatedSubject)
        Attach the specified listener to the specified subject, so that when dependencies are being prepared, notifying the listener will be considered equivalent to notifying the subject. This makes it possible to support multiple listeners in a single subject, typically using inner classes.

        For example, the CompositeList class uses multiple listeners for a single subject, and uses this method to define that relationship.

      • clearRelatedSubject

        void clearRelatedSubject​(java.lang.Object listener)
        Detach the listener from its related subject.
      • setRelatedListener

        void setRelatedListener​(java.lang.Object subject,
                                java.lang.Object relatedListener)
        Attach the specified subject to the specified listener, so that the listener's dependencies are satisfied before the subject is notified. This makes it possible for a single listener to have multiple subjects, typically using inner classes.

        For example, the ListSelection class uses a single listener for multiple subjects (selected and unselected), and uses this method to define that relationship.

      • clearRelatedListener

        void clearRelatedListener​(java.lang.Object subject,
                                  java.lang.Object relatedListener)
        Detach the subject from its related listener.
