Class Restriction

java.lang.Object

chameleon.rss.media.Restriction

public class Restriction
extends Object

Allows restrictions to be placed on the aggregator rendering the media in the feed. Currently, restrictions are based on distributor (uri) and country codes. This element is purely informational and no obligation can be assumed or implied. Only one media restriction element of the same type can be applied to a media object - all others will be ignored. Entities in this element should be space separated. To allow the producer to explicitly declare his/her intentions, two literals are reserved: 'all', 'none'. These literals can only be used once.
Example:

 <media:restriction relationship="allow" type="country">au us</media:restriction>
 

Note: if the restriction element is empty and the type of relationship is "allow", it is assumed that the empty list means "allow nobody" and the media should not be syndicated.
