JXTA in a Nutshell

Name

PeerInfoService

Synopsis

The peer information service is used to find peer information advertisements for peers that belong to a specific peergroup. Instances of this class are returned by the peergroup’s getPeerInfoService( ) method.

Discovery of peer information advertisements is asynchronous. You call the getRemotePeerInfo( ) method to find information about particular peers. That information can be retrieved later by calling the getPeerInfo( ) method (which will retrieve it from the local cache held by the application), or you can register a peer information listener to be notified when the advertisement is found.

To find a specific peer, pass its peer ID to one of the getter methods. To find all peers, pass null to one of the getter methods.
