Constructor Detail

ConstrainableLandlordLease

public ConstrainableLandlordLease(Uuid cookie,
                                  Landlord landlord,
                                  Uuid landlordUuid,
                                  long expiration,
                                  MethodConstraints methodConstraints)

Create a new ConstrainableLandlordLease.

Parameters:

cookie - a Uuid that universally and uniquely identifies the lease this object is to be a proxy for

landlord - Landlord object that will be used to communicate renew and cancel requests to the granter of the lease.

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 two leases can be batched together.

expiration - The initial expiration time of the lease in milliseconds since the beginning of the epoch.

methodConstraints - the client method constraints to place on this proxy (may be null).

Throws:

NullPointerException - if landlord, landlordUuid, or cookie is null.

ClassCastException - if landlord does not implement RemoteMethodControl.
