-// OVERVIEW: |
-// |
-// A container for a list of callbacks. Unlike a normal STL vector or list, |
-// this container can be modified during iteration without invalidating the |
-// iterator. It safely handles the case of a callback removing itself |
-// or another callback from the list while callbacks are being run. |
-// |
-// TYPICAL USAGE: |
-// |
-// class MyWidget { |
-// public: |
-// ... |
-// |
-// typedef base::Callback<void(const Foo&)> OnFooCallback; |
-// |
-// scoped_ptr<base::CallbackRegistry<void(const Foo&)>::Subscription> |
-// RegisterCallback(const OnFooCallback& cb) { |
-// return callback_registry_.Add(cb); |
-// } |
-// |
-// private: |
-// void NotifyFoo(const Foo& foo) { |
-// callback_registry_.Notify(foo); |
-// } |
-// |
-// base::CallbackRegistry<void(const Foo&)> callback_registry_; |
-// }; |
-// |
-// |
-// class MyWidgetListener { |
-// public: |
-// MyWidgetListener::MyWidgetListener() { |
-// foo_subscription_ = MyWidget::GetCurrent()->RegisterCallback( |
-// base::Bind(&MyWidgetListener::OnFoo, this))); |
-// } |
-// |
-// MyWidgetListener::~MyWidgetListener() { |
-// // Subscription gets deleted automatically and will deregister |
-// // the callback in the process. |
-// } |
-// |
-// private: |
-// void OnFoo(const Foo& foo) { |
-// // Do something. |
-// } |
-// |
-// scoped_ptr<base::CallbackRegistry<void(const Foo&)>::Subscription> |
-// foo_subscription_; |
