All Implemented Interfaces:

LeaseContext, Externalizable, Serializable, Lease

public class LeaseProxy
extends Object
implements LeaseContext, Externalizable

An instance of this class represents an entry/template lease or a lease of an event registration results from a notify.
You can get entry UID from the entry Lease object. e.g.

 Lease lease = space.write(o, null, Lease.FOREVER);
 LeaseProxy lp = (LeaseProxy) lease;
 String uid = lp.getUID();
