Class TwitterResource

java.lang.Object
  org.atmosphere.samples.twitter.TwitterResource

@Singleton
public class TwitterResource
extends Object

Twitter like Comet application. This rest based web application implements the logic needed to support micro blogging a la Twitter.com. Users can blog about what they are doing and can also follow their friends. When an update is made by one user, all its follower gets updated automatically. The updated words can be moved on the screen and all follower will see the move. This Singleton demonstrate how multiple Broadcaster can be used to easily isolate suspended connection and to only push messages to a subset of those suspended connection using the Suspend annotation. There is one AtmosphereResourceEvent per user. AtmosphereResourceEvent associated with the user suspended connection are added to their Broadcaster and added to the Broadcaster of the users they are following.
