+/**
+ * The system that constructs the "shade list", the filtered, grouped, and sorted list of
+ * notifications that are currently being displayed to the user in the notification shade.
+ *
+ * The pipeline proceeds through a series of stages in order to produce the final list (see below).
+ * Each stage exposes hooks and listeners to allow other code to participate.
+ *
+ * This list differs from the canonical one we receive from system server in a few ways:
+ * - Filtered: Some notifications are filtered out. For example, we filter out notifications whose
+ *   views haven't been inflated yet. We also filter out some notifications if we're on the lock
+ *   screen and notifications for other users. So participate, see
+ *   {@link #addPreGroupFilter} and similar methods.
+ * - Grouped: Notifications that are part of the same group are clustered together into a single
+ *   GroupEntry. These groups are then transformed in order to remove children or completely split
+ *   them apart. To participate, see {@link #addPromoter}.
+ * - Sorted: All top-level notifications are sorted. To participate, see
+ *   {@link #setSections} and {@link #setComparators}
+ *
+ * The exact order of all hooks is as follows:
+ *  0. Collection listeners are fired ({@link #addCollectionListener}).
+ *  1. Pre-group filters are fired on each notification ({@link #addPreGroupFilter}).
+ *  2. Initial grouping is performed (NotificationEntries will have their parents set
+ *     appropriately).
+ *  3. OnBeforeTransformGroupListeners are fired ({@link #addOnBeforeTransformGroupsListener})
+ *  4. NotifPromoters are called on each notification with a parent ({@link #addPromoter})
+ *  5. OnBeforeSortListeners are fired ({@link #addOnBeforeSortListener})
+ *  6. Top-level entries are assigned sections by NotifSections ({@link #setSections})
+ *  7. Top-level entries within the same section are sorted by NotifComparators
+ *     ({@link #setComparators})
+ *  8. Pre-render filters are fired on each notification ({@link #addPreRenderFilter})
+ *  9. OnBeforeRenderListListeners are fired ({@link #addOnBeforeRenderListListener})
+ *  9. The list is handed off to the view layer to be rendered

-/**
- * The system that constructs the current "notification list", the list of notifications that are
- * currently being displayed to the user.
- *
- * The pipeline proceeds through a series of stages in order to produce the final list (see below).
- * Each stage exposes hooks and listeners for other code to participate.
- *
- * This list differs from the canonical one we receive from system server in a few ways:
- * - Filtered: Some notifications are filtered out. For example, we filter out notifications whose
- *   views haven't been inflated yet. We also filter out some notifications if we're on the lock
- *   screen. To participate, see {@link #addFilter(NotifFilter)}.
- * - Grouped: Notifications that are part of the same group are clustered together into a single
- *   GroupEntry. These groups are then transformed in order to remove children or completely split
- *   them apart. To participate, see {@link #addPromoter(NotifPromoter)}.
- * - Sorted: All top-level notifications are sorted. To participate, see
- *   {@link #setSectionsProvider(SectionsProvider)} and {@link #setComparators(List)}
- *
- * The exact order of all hooks is as follows:
- *  0. Collection listeners are fired (see {@link NotifCollection}).
- *  1. NotifFilters are called on each notification currently in NotifCollection.
- *  2. Initial grouping is performed (NotificationEntries will have their parents set
- *     appropriately).
- *  3. OnBeforeTransformGroupListeners are fired
- *  4. NotifPromoters are called on each notification with a parent
- *  5. OnBeforeSortListeners are fired
- *  6. SectionsProvider is called on each top-level entry in the list
- *  7. The top-level entries are sorted using the provided NotifComparators (plus some additional
- *     built-in logic).
- *  8. OnBeforeRenderListListeners are fired
- *  9. The list is handed off to the view layer to be rendered.
