JXTA in a Nutshell

Name

AdvertisementFactory.Instantiator

Synopsis

Classes that implement this interface are called by the AdvertisementFactory to create specific advertisment types. The standard advertisement types have a default instantiator that they use (transparent to the developer); if you create your own advertisement class, then you must create an appropriate instantiator for it. The instantiator class must be named Instantiator and be an inner class of your advertisement class; e.g., if your class is named MyAdv, then your instantiator would be called MyAdv.Instantiator.
