Class DeformedClientLeaseMapWrapper
java.lang.Object
com.sun.jini.lease.AbstractLeaseMap
com.sun.jini.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.

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
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
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
