| /** |
| * This interface supplies all UI-specific behavior of the window manager. An |
| * instance of it is created by the window manager when it starts up, and allows |
| * customization of window layering, special window types, key dispatching, and |
| * layout. |
| * |
| * <p>Because this provides deep interaction with the system window manager, |
| * specific methods on this interface can be called from a variety of contexts |
| * with various restrictions on what they can do. These are encoded through |
| * a suffixes at the end of a method encoding the thread the method is called |
| * from and any locks that are held when it is being called; if no suffix |
| * is attached to a method, then it is not called with any locks and may be |
| * called from the main window manager thread or another thread calling into |
| * the window manager. |
| * |
| * <p>The current suffixes are: |
| * |
| * <dl> |
| * <dt> Ti <dd> Called from the input thread. This is the thread that |
| * collects pending input events and dispatches them to the appropriate window. |
| * It may block waiting for events to be processed, so that the input stream is |
| * properly serialized. |
| * <dt> Tq <dd> Called from the low-level input queue thread. This is the |
| * thread that reads events out of the raw input devices and places them |
| * into the global input queue that is read by the <var>Ti</var> thread. |
| * This thread should not block for a long period of time on anything but the |
| * key driver. |
| * <dt> Lw <dd> Called with the main window manager lock held. Because the |
| * window manager is a very low-level system service, there are few other |
| * system services you can call with this lock held. It is explicitly okay to |
| * make calls into the package manager and power manager; it is explicitly not |
| * okay to make calls into the activity manager or most other services. Note that |
| * {@link android.content.Context#checkPermission(String, int, int)} and |
| * variations require calling into the activity manager. |
| * <dt> Li <dd> Called with the input thread lock held. This lock can be |
| * acquired by the window manager while it holds the window lock, so this is |
| * even more restrictive than <var>Lw</var>. |
