JXTA in a Nutshell

Name

Advertisement

Synopsis

Advertisements are core JXTA objects that advertise all JXTA resources (peers, peergroups, pipes, and so on). They provide a platform-independent representation of core platform objects.

Advertisements contain text documents that hold the contents of the advertisement; a document can be extracted from an advertisement with the getDocument( ) method with a MIME type of “text/xml” or “text/plain.”

Advertisements carry a timeout value, which is the number of seconds during which the advertisement is valid. Entities that cache advertisements should purge advertisements after that number of seconds have elapsed.

Subclasses of this type are expected to override the getAdvertisementType( ) method and return a name that uniquely identifies the advertisement type.
