Class DeformedClientLeaseMapWrapper

java.lang.Object

org.apache.river.lease.AbstractLeaseMap

org.apache.river.norm.DeformedClientLeaseMapWrapper

All Implemented Interfaces:

Map, LeaseMap

class DeformedClientLeaseMapWrapper
extends AbstractLeaseMap

An implementation of LeaseMap that holds exactly one lease. Used when we have a deformed lease that we won't be able to batch with anyone else and we want to call ClientLeaseWrapper.renew() instead of LeaseMap.renewAll().

Provides hooks for synchronization and data associated with each client lease while allowing us to use LeaseRenewalManager. Objects of this class are returned by createLeaseMap calls made on ClientLeaseWrapper objects that are deformed.

Constructor Detail

DeformedClientLeaseMapWrapper

DeformedClientLeaseMapWrapper(ClientLeaseWrapper lease,
                              long duration)

Create a DeformedClientLeaseMapWrapper.

Parameters:

lease - a Wrapper for the lease that wants to be renewed. May be deformed.

duration - the duration to associate with lease

Method Detail

cancelAll

public void cancelAll()

Description copied from interface: LeaseMap

Cancels all leases in the LeaseMap. If all cancels are successful, returns normally (leaving all leases in the map). Otherwise, removes all leases that failed to cancel from the LeaseMap, and throws LeaseMapException.

renewAll

public void renewAll()
              throws LeaseMapException,
                     RemoteException

Description copied from interface: LeaseMap

Renews all leases in the LeaseMap, using their current values as the renewal durations. If all renewals are successful, returns normally. Otherwise, removes all leases that failed to renew from the LeaseMap, and throws LeaseMapException.

Throws:

LeaseMapException

RemoteException

renewAl

private void renewAl()
              throws LeaseMapException,
                     RemoteException

Throws:

LeaseMapException

RemoteException

canContainKey

public boolean canContainKey(Object key)

Description copied from interface: LeaseMap

Returns true if the given object is a Lease which can be renewed and cancelled in a batch with other leases in the map. Whether or not two Lease objects can be batched is an implementation detail determined by the objects.

Parameters:

key - an object that should be a lease

Returns:

true if the lease can be renewed and cancelled in a a batch with other leases
