Interface LeaseRenewalService

public interface LeaseRenewalService

Interface to the lease renewal service. The interface is not a remote interface; each implementation of the renewal service exports proxy objects that implement the LeaseRenewalService interface that use an implementation-specific protocol to communicate with the actual remote server. All of the proxy methods obey normal RMI remote interface semantics. Two proxy objects are equal if they are proxies for the same renewal service. Every method invocation (on both a LeaseRenewalService and any LeaseRenewalSet it has created) is atomic with respect to other invocations.
