| /** |
| * Mediates requests related to the keyguard. This includes queries about the |
| * state of the keyguard, power management events that effect whether the keyguard |
| * should be shown or reset, callbacks to the phone window manager to notify |
| * it of when the keyguard is showing, and events from the keyguard view itself |
| * stating that the keyguard was succesfully unlocked. |
| * |
| * Note that the keyguard view is shown when the screen is off (as appropriate) |
| * so that once the screen comes on, it will be ready immediately. |
| * |
| * Example queries about the keyguard: |
| * - is {movement, key} one that should wake the keygaurd? |
| * - is the keyguard showing? |
| * - are input events restricted due to the state of the keyguard? |
| * |
| * Callbacks to the phone window manager: |
| * - the keyguard is showing |
| * |
| * Example external events that translate to keyguard view changes: |
| * - screen turned off -> reset the keyguard, and show it so it will be ready |
| * next time the screen turns on |
| * - keyboard is slid open -> if the keyguard is not secure, hide it |
| * |
| * Events from the keyguard view: |
| * - user succesfully unlocked keyguard -> hide keyguard view, and no longer |
| * restrict input events. |
| * |
| * Note: in addition to normal power managment events that effect the state of |
| * whether the keyguard should be showing, external apps and services may request |
| * that the keyguard be disabled via {@link #setKeyguardEnabled(boolean)}. When |
| * false, this will override all other conditions for turning on the keyguard. |
| * |
| * Threading and synchronization: |
| * This class is created by the initialization routine of the {@link android.view.WindowManagerPolicy}, |
| * and runs on its thread. The keyguard UI is created from that thread in the |
| * constructor of this class. The apis may be called from other threads, including the |
| * {@link com.android.server.input.InputManagerService}'s and {@link android.view.WindowManager}'s. |
| * Therefore, methods on this class are synchronized, and any action that is pointed |
| * directly to the keyguard UI is posted to a {@link android.os.Handler} to ensure it is taken on the UI |
| * thread of the keyguard. |
