This class abstracts the the implementations used to represent and create advertisements. <p/>Advertisements are core objects that are used to advertise a Peer, a PeerGroup, a Service, or a PipeServiceImpl. The Advertisement class provides a platform independent representation of core objects that can be exchanged between different implementations (Java, C). <p/>The AdvertisementFactory extends the ClassFactory to register the various types of adverstisements into a static hastable. The factory is called with the Advertisement type requested to create the corresponding advertisement type. <p/>The initial set of Advertisement instances is loaded from the java property "net.jxta.impl.config.AdvertisementInstanceTypes" <p/>It would be nice to have "newAdvertisement" methods for "Document" and "TextDocument", but this is not feasible because "TextElement" got there first.<P><P><DL><DT><B>See Also:</B><DD><A HREF="../../../net/jxta/document/Advertisement.html" title="class in net.jxta.document"><CODE>Advertisement</CODE></A>, <A
