Examples of net.jini.core.lease.Lease.cancel()

net.jini.core.lease.Lease.cancel()
Used by the lease holder to indicate that it is no longer interested in the resource or information held by the lease. If the leased information or resource could cause a callback to the lease holder (or some other object on behalf of the lease holder), the lease grantor should not issue such a callback after the lease has been cancelled. The overall effect of a cancel call is the same as lease expiration, but instead of happening at the end of a pre-agreed duration it happens immediately. @throws UnknownLeaseException the lease being cancelled is unknownto the lease grantor @throws RemoteException
