-/**
- * 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 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 Handler} to ensure it is taken on the UI
- * thread of the keyguard.
