- * - * Since I can't sprinkle the Collections interface - * documentation with special information for BeanContext - * implementors, I'll have to document special requirements for - * implementors of those functions here. - *

- * - * add() or addAll(): - *
- *

    - *
  1. - * May add any Object into the hierarchy as well as a - * BeanContextChild, BeanContext or - * BeanContextProxy object. - * This way, any Bean can be in the hierarchy. - *
    2. - *
  2. - * Must synchronize on BeanContext.globalHierarchyLock. - *
    3. - *
  3. - * Don't add the Object if it's already there (only once - * per BeanContext). - *
    4. - *
  4. - * If it is a BeanContextChild implementor, call - * setBeanContext() on it. If it's a - * BeanContextProxy implementor, call - * getBeanContextProxy().setBeanContext() on it. - * If setBeanContext() vetoes the change, back out - * all changes so far and throw IllegalStateException. - *
    5. - *
  5. - * If it (or its proxy) implements Visibility, call - * dontUseGui() or okToUseGui() on it, - * depending on whether you (the BeanContext) feel like - * allowing it to use the GUI or not. - *
    6. - *
  6. - * If it implements BeanContextChild or - * BeanContextProxy, register yourself (the - * BeanContext) as both a - * PropertyChangeListener and - * VetoableChangeListener on the "beanContext" - * property (it may also add itself on any other properties it wishes - * to). - *
    7. - *
  7. - * If it is a listener or event source that you (the - * BeanContext) are interested in, you may register - * yourself to it or register it to you. - *
    8. - *
  8. - * Fire a java.beans.beancontext.BeanContextMembershipEvent - * before exiting. addAll() should wait until everything - * is done changing before firing the event (or events) so that if a - * failure occurs, the backing-out process can proceed without any - * events being fired at all. - *
    9. - *
- *

- * - * remove() or removeAll(): - *
- *

    - *
  1. - * Must synchronize on BeanContext.globalHierarchyLock. - *
    2. - *
  2. - * If the specified Object is not a child of this - * BeanContext, just exit without performing any actions. - *
    3. - *
  3. - * Remove the Object from your collection of children. - *
    4. - *
  4. - * If it is a BeanContextChild implementor, call - * setBeanContext(null) on it. If it's a - * BeanContextProxy implementor, call - * getBeanContextProxy().setBeanContext(null) on it. - * If setBeanContext() vetoes the change, back out - * all changes so far and throw IllegalStateException. - *
    5. - *
  5. - * If you registered the Object to listen to you or - * registered yourself as a listener on the Object during - * add() or addAll(), undo the registration - * bycalling the appropriate removeListener() method. - *
    6. - *
  6. - * Fire a java.beans.beancontext.BeanContextMembershipEvent - * before exiting. removeAll() should wait until - * everything is done changing before firing the event (or events) so - * that if a failure occurs, the backing-out process can proceed - * without any events being fired at all. - *
    7. - *
- *

- * - * addAll(), removeAll(), - * retainAll() and clear() do not need to be - * implemented, but may be if so desired. - *

- * - * Similarly, Visibility and DesignMode methods - * should propagate changed values to children that implement interfaces - * of the same name. - *
