Event objects are passed as parameters to event listeners when an event occurs. This is Starling's version of the Flash Event class.

EventDispatchers create instances of this class and send them to registered listeners. An event object contains information that characterizes an event, most importantly the event type and if the event bubbles. The target of an event is the object that dispatched it.

For some event types, this information is sufficient; other events may need additional information to be carried to the listener. In that case, you can subclass "Event" and add properties with all the information you require. The "EnterFrameEvent" is an example for this practice; it adds a property about the time that has passed since the last frame.

Furthermore, the event class contains methods that can stop the event from being processed by other listeners - either completely or at the next bubble stage.
