Examples of net.jini.core.lookup.ServiceRegistrar

net.jini.core.lookup.ServiceRegistrar
Defines the interface to the lookup service. The interface is not a remote interface; each implementation of the lookup service exports proxy objects that implement the ServiceRegistrar interface local to the client, using an implementation-specific protocol to communicate with the actual remote server. All of the proxy methods obey normal RMI remote interface semantics except where explicitly noted. Two proxy objects are equal if they are proxies for the same lookup service. Every method invocation (on both ServiceRegistrar and ServiceRegistration) is atomic with respect to other invocations. @author Sun Microsystems, Inc. @see ServiceRegistration @since 1.0
