| 39 | * Coordinates hiding, intercepting (the dismissal), and deletion of bubbled notifications. |
| 40 | * |
| 41 | * The typical "start state" for a bubbled notification is when a bubble-able notification is |
| 42 | * posted. It is visible as a bubble AND as a notification in the shade. From here, we can get |
| 43 | * into a few hidden-from-shade states described below: |
| 44 | * |
| 45 | * Start State -> Hidden from shade |
| 46 | * User expands the bubble so we hide its notification from the shade. |
| 47 | * OR |
| 48 | * User dismisses a group summary with a bubbled child. All bubbled children are now hidden from |
| 49 | * the shade. And the group summary's dismissal is intercepted + hidden from the shade (see below). |
| 50 | * |
| 51 | * Start State -> Dismissal intercepted + hidden from shade |
| 52 | * User dismisses the notification from the shade. We now hide the notification from the shade |
| 53 | * and intercept its dismissal (the removal signal is never sent to system server). We |
| 54 | * keep the notification alive in system server so that {@link BubbleController} can still |
| 55 | * respond to app-cancellations (ie: remove the bubble if the app cancels the notification). |
