+/**
+ * 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.KeyInputQueue}'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.
