Method Detail

getRenewalSetLease

public Lease getRenewalSetLease()

Convenience method to retrieve the Lease associated with the source of this event. This is the Lease which is about to expire.

The Lease object returned will be equivalent (in the sense of equals) to other Lease objects associated with the set, but may not be the same object. One notable consequence of having two different objects is that the getExpiration method of the Lease object returned by this method may return a different time than the getExpiration methods of other Lease objects granted on the same set.

The expiration time associated with the Lease object returned by this method will reflect the expiration the lease had when the event occurred. Renewal calls may have changed the expiration time of the underlying lease between the time when the event was generated and when it was delivered.

Returns:

the lease associated with the source of this event
