I have a parent object, with multiple child objects.Every child object is of the same type and has a ChildMethod that contains some child specific logic.If the ChildMethod is called on any child, i want to serialize the state of all children.I put that logic into the parent object.Also I implemented it with the observer pattern, the children being the subjects, and the parent the observer.It works fine so far.Now I need another method CallAllChildMethods, that basically calls the ChildMethod on every child, yet I want to avoid multiple serializations, since it is necessary to do it only once.The only solution I see at the moment is to unsubscribe to all subjectevents before calling CallAllChildMethods, then resubscribe again.That works but is a heavy design smell.Are there, from a design standpoint, cleaner ways to handle that case?
