-/**
- * This class injects accessibility into WebViews with disabled JavaScript or

- * script to inject.
- * </p>
- * Note: To avoid changes in the framework upon changing the available
- * navigation axis, or reordering the navigation axis, or changing
- * the key bindings, or defining sequence of actions to be bound to
- * a given key this class is navigation axis agnostic. It is only
- * aware of one navigation axis which is in fact the default behavior
- * of webViews while using the DPAD/TrackBall.
- * </p>
- * In general a key binding is a mapping from modifiers + key code to
- * a sequence of actions. For more detail how to specify key bindings refer to
- * {@link android.provider.Settings.Secure#ACCESSIBILITY_WEB_CONTENT_KEY_BINDINGS}.
- * </p>
- * The possible actions are invocations to
- * {@link #setCurrentAxis(int, boolean, String)}, or
- * {@link #traverseGivenAxis(int, int, boolean, String, boolean)}
- * {@link #performAxisTransition(int, int, boolean, String)}
- * referred via the values of:

- * {@link #ACTION_TRAVERSE_CURRENT_AXIS},
- * {@link #ACTION_TRAVERSE_GIVEN_AXIS},
- * {@link #ACTION_PERFORM_AXIS_TRANSITION},
- * respectively.
- * The arguments for the action invocation are specified as offset
- * hexademical pairs. Note the last argument of the invocation
- * should NOT be specified in the binding as it is provided by
- * this class. For details about the key binding implementation
- * refer to {@link AccessibilityWebContentKeyBinding}.

-/**
- * Perform asynchronous dispatch of input events in a {@link WebView}.
- *
- * This dispatcher is shared by the UI thread ({@link WebViewClassic}) and web kit
- * thread ({@link WebViewCore}). The UI thread enqueues events for
- * processing, waits for the web kit thread to handle them, and then performs
- * additional processing depending on the outcome.
- *
- * How it works:
- *
- * 1. The web view thread receives an input event from the input system on the UI
- * thread in its {@link WebViewClassic#onTouchEvent} handler. It sends the input event
- * to the dispatcher, then immediately returns true to the input system to indicate that
- * it will handle the event.
- *
- * 2. The web kit thread is notified that an event has been enqueued. Meanwhile additional
- * events may be enqueued from the UI thread. In some cases, the dispatcher may decide to
- * coalesce motion events into larger batches or to cancel events that have been
- * sitting in the queue for too long.
- *
- * 3. The web kit thread wakes up and handles all input events that are waiting for it.
- * After processing each input event, it informs the dispatcher whether the web application
- * has decided to handle the event itself and to prevent default event handling.
- *
- * 4. If web kit indicates that it wants to prevent default event handling, then web kit
- * consumes the remainder of the gesture and web view receives a cancel event if
- * needed. Otherwise, the web view handles the gesture on the UI thread normally.
- *
- * 5. If the web kit thread takes too long to handle an input event, then it loses the
- * right to handle it. The dispatcher synthesizes a cancellation event for web kit and
- * then tells the web view on the UI thread to handle the event that timed out along
- * with the rest of the gesture.
- *
- * One thing to keep in mind about the dispatcher is that what goes into the dispatcher
- * is not necessarily what the web kit or UI thread will see. As mentioned above, the
- * dispatcher may tweak the input event stream to improve responsiveness. Both web view and
- * web kit are guaranteed to perceive a consistent stream of input events but
- * they might not always see the same events (especially if one decides
- * to prevent the other from handling a particular gesture).
- *
- * This implementation very deliberately does not refer to the {@link WebViewClassic}
- * or {@link WebViewCore} classes, preferring to communicate with them only via
- * interfaces to avoid unintentional coupling to their implementation details.
- *
- * Currently, the input dispatcher only handles pointer events (includes touch,
- * hover and scroll events). In principle, it could be extended to handle trackball
- * and key events if needed.
