Constructor Detail

ConstrainableLandlordLeaseMap

ConstrainableLandlordLeaseMap(Landlord landlord,
                              Uuid landlordUuid,
                              LandlordLease lease,
                              long duration)

Create a new ConstrainableLandlordLeaseMap.

Parameters:

landlord - Reference to the entity that created lease. Assumes that any necessary method constraints have been attached.

landlordUuid - a universally unique id that has been assigned to the server granting of the lease. Ideally the Uuid landlord.getUuid would return if landlord implemented ReferentUuid. Used to determine when leases can be added to this map.

lease - First lease to be placed in the map. It is assumed that canContainKey(lease) would be true. Must work with the landlord protocol.

duration - The duration the lease should be renewed for if renewAll is called.

Throws:

ClassCastException - if landlord does not implement RemoteMethodControl.

NullPointerException - if landlord is null.
