Detailed Description

The InitializingMembershipListener is a MembershipListener that will first receives a InitialMembershipEvent when it is registered so it immediately knows which members are available.

After that event has been received, it will receive the normal MembershipEvents.

When the InitializingMembershipListener already is registered on a Cluster and is registered again on the same Cluster instance, it will not receive an additional MembershipInitializeEvent. So this is a once only event.

Warning 1: If listener should do a time consuming operation, off-load the operation to another thread. otherwise it will slow down the system.

Warning 2: Do not make a call to hazelcast. It can cause deadlock.
