+/**
+ * {@link NotifBindPipeline} is responsible for converting notifications from their data form to
+ * their actual inflated views. It is essentially a control class that composes notification view
+ * binding logic (i.e. {@link BindStage}) in response to explicit bind requests. At the end of the
+ * pipeline, the notification's bound views are guaranteed to be correct and up-to-date, and any
+ * registered callbacks will be called.
+ *
+ * The pipeline ensures that a notification's top-level view and its content views are bound.
+ * Currently, a notification's top-level view, the {@link ExpandableNotificationRow} is essentially
+ * just a {@link FrameLayout} for various different content views that are switched in and out as
+ * appropriate. These include a contracted view, expanded view, heads up view, and sensitive view on
+ * keyguard. See {@link InflationFlag}. These content views themselves can have child views added
+ * on depending on different factors. For example, notification actions and smart replies are views
+ * that are dynamically added to these content views after they're inflated. Finally, aside from
+ * the app provided content views, System UI itself also provides some content views that are shown
+ * occasionally (e.g. {@link NotificationGuts}). Many of these are business logic specific views
+ * and the requirements surrounding them may change over time, so the pipeline must handle
+ * composing the logic as necessary.
+ *
+ * Note that bind requests do not only occur from add/updates from updates from the app. For
+ * example, the user may make changes to device settings (e.g. sensitive notifications on lock
+ * screen) or we may want to make certain optimizations for the sake of memory or performance (e.g
+ * freeing views when not visible). Oftentimes, we also need to wait for these changes to complete
+ * before doing something else (e.g. moving a notification to the top of the screen to heads up).
+ * The pipeline thus handles bind requests from across the system and provides a way for
+ * requesters to know when the change is propagated to the view.
+ *
+ * Right now, we only support one attached {@link BindStage} which just does all the binding but we
+ * should eventually support multiple stages once content inflation is made more modular.
+ * In particular, row inflation/binding, which is handled by {@link NotificationRowBinder} should
+ * probably be moved here in the future as a stage. Right now, the pipeline just manages content
+ * views and assumes that a row is given to it when it's inflated.
