public class WOSMILSwitch

extends WOSMILElement

WOSMILSwitch creates content for the SMIL "switch" element. A "switch" element contains other elements (typically media objects, synchronization elements, and layout elements) that should only appear if certain client-side synchonization element tests pass. This way, all available media element specifications are delivered to the client and the client determines which media elements should be instantiated.

Example: Imagine a situation where multiple movies available on a Web server, each encoded for a different bit rate and you have a model and database in place that contains each movie and the URL and bitrate encoding of the movie. A simple way to make sure that the client gets the movie of the proper bit-rate is to create a WORepetition inside a WOSMILSwitch element. In the repetition, place a WOSMILMediaObject and bind the element's href to aMovie.url and bind the element's systemBitRate to aMovie.bitRate. The client plays the movie whose systemBitRate is no higher than the rate the system can can handle.
