Examples of net.jini.core.lease.Lease

net.jini.core.lease.Lease
The Lease interface defines a type of object that is returned to the lease holder and issued by the lease grantor. Particular instances of the Lease type will be created by the grantors of a lease, and returned to the holder of the lease as part of the return value from a call that allocates a leased resource. The call that requests a leased resource will typically include a requested duration for the lease. If the request is for a particular duration, the lease grantor is required to grant a lease of no more than the requested period of time. A lease may be granted for a period of time shorter than that requested. @author Sun Microsystems, Inc. @since 1.0
