- * @fileoverview A patched, standardized event object for browser events.
- *
- * <pre>
- * The patched event object contains the following members:
- * - type           {string}    Event type, e.g. 'click'
- * - target         {Object}    The element that actually triggered the event
- * - currentTarget  {Object}    The element the listener is attached to
- * - relatedTarget  {Object}    For mouseover and mouseout, the previous object
- * - offsetX        {number}    X-coordinate relative to target
- * - offsetY        {number}    Y-coordinate relative to target
- * - clientX        {number}    X-coordinate relative to viewport
- * - clientY        {number}    Y-coordinate relative to viewport
- * - screenX        {number}    X-coordinate relative to the edge of the screen
- * - screenY        {number}    Y-coordinate relative to the edge of the screen
- * - button         {number}    Mouse button. Use isButton() to test.
- * - keyCode        {number}    Key-code
- * - ctrlKey        {boolean}   Was ctrl key depressed
- * - altKey         {boolean}   Was alt key depressed
- * - shiftKey       {boolean}   Was shift key depressed
- * - metaKey        {boolean}   Was meta key depressed
- * - defaultPrevented {boolean} Whether the default action has been prevented
- * - state          {Object}    History state object
- *
- * NOTE: The keyCode member contains the raw browser keyCode. For normalized
- * key and character code use {@link goog.events.KeyHandler}.
- * </pre>

-/**
- * @fileoverview An event manager for both native browser event
- * targets and custom JavaScript event targets
- * ({@code goog.events.Listenable}). This provides an abstraction
- * over browsers' event systems.
- *
- * It also provides a simulation of W3C event model's capture phase in
- * Internet Explorer (IE 8 and below). Caveat: the simulation does not
- * interact well with listeners registered directly on the elements
- * (bypassing goog.events) or even with listeners registered via
- * goog.events in a separate JS binary. In these cases, we provide
- * no ordering guarantees.
- *
- * The listeners will receive a "patched" event object. Such event object
- * contains normalized values for certain event properties that differs in
- * different browsers.
- *
- * Example usage:
- * <pre>
- * goog.events.listen(myNode, 'click', function(e) { alert('woo') });
- * goog.events.listen(myNode, 'mouseover', mouseHandler, true);
- * goog.events.unlisten(myNode, 'mouseover', mouseHandler, true);
- * goog.events.removeAll(myNode);
- * </pre>
- *
- *                                            in IE and event object patching]

-// IMPLEMENTATION NOTES:
-// goog.events stores an auxiliary data structure on each EventTarget
-// source being listened on. This allows us to take advantage of GC,
-// having the data structure GC'd when the EventTarget is GC'd. This
-// GC behavior is equivalent to using W3C DOM Events directly.

-/**
- * A listenable interface. A listenable is an object with the ability
- * to dispatch/broadcast events to "event listeners" registered via
- * listen/listenOnce.
- *
- * The interface allows for an event propagation mechanism similar
- * to one offered by native browser event targets, such as
- * capture/bubble mechanism, stopping propagation, and preventing
- * default actions. Capture/bubble mechanism depends on the ancestor
- * tree constructed via {@code #getParentEventTarget}; this tree
- * must be directed acyclic graph. The meaning of default action(s)
- * in preventDefault is specific to a particular use case.
- *
- * Implementations that do not support capture/bubble or can not have
- * a parent listenable can simply not implement any ability to set the
- * parent listenable (and have {@code #getParentEventTarget} return
- * null).
- *
- * Implementation of this class can be used with or independently from
- * goog.events.
- *
- * Implementation must call {@code #addImplementation(implClass)}.
