This annotation should be used on methods that need to be notified when the
ConsistentHash
implementation
in use by the
DistributionManager
changes due to a change in cluster topology.
This is not fired for
CacheMode.LOCAL
caches.
Methods annotated with this annotation should accept a single parameter, a
TopologyChangedEvent
otherwise a
IncorrectListenerException
will be thrown when registering your listener.
Note that methods marked with this annotation will be fired
before and
after the updated
ConsistentHash
is installed, i.e., your method will be called twice, with
Event.isPre()
being set to
true as well
as
false.
