Interfaces
  InterfaceDescription

Public interfaceIAtomicLong
IAtomicLong is a redundant and highly available distributed Atomic Long
Public interfaceIClient
IClient interface allows to get information about a connected clients socket address, type and uuid.
Public interfaceIClientListener
IClientListener allows to get notified when a IClient is connected to or disconnected from cluster.
Public interfaceIClientService
IClientService allows to query connected IClient s and attach/detach IClientListener s to listen connection events.
Public interfaceICluster
Hazelcast cluster interface.
Public interfaceICountDownLatch
ICountDownLatch is a backed-up distributed alternative to the .

ICountDownLatch is a cluster-wide synchronization aid that allows one or more threads to wait until a set of operations being performed in other threads completes.

There are a few differences compared to the ICountDownLatch :

  1. the ICountDownLatch count can be re-set using TrySetCount(int) after a countdown has finished but not during an active count. This allows the same latch instance to be reused.
  2. there is no await() method to do an unbound wait since this is undesirable in a distributed application: it can happen that for example a cluster is split or that the master and replica's all die. So in most cases it is best to configure an explicit timeout so have the ability to deal with these situations.
Public interfaceIDistributedObject
Base interface for all distributed objects.
Public interfaceIDistributedObjectListener
IDistributedObjectListener allows to get notified when a IDistributedObject is created or destroyed cluster-wide.
Public interfaceIEndpoint
Endpoint represents a peer in the cluster.

Public interfaceIExecutorService
Distributed implementation of ExecutorService. IExecutorService provides additional methods like executing tasks on a specific member, on a member who is owner of a specific key, executing a tasks on multiple members and listening execution result using a callback.
Public interfaceIHazelcastInstance
Hazelcast instance.
Public interfaceIHazelcastInstanceAware

Public interfaceIHCollectionT

Public interfaceIHListT
Concurrent, distributed implementation of IListTIList
Public interfaceIHSetT
Concurrent, distributed implementation of ISet
Public interfaceIIdGenerator
Cluster-wide unique id generator.
Public interfaceIInitialMembershipListener
The InitializingMembershipListener is a IMembershipListener 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 ICluster and is registered again on the same ICluster instance, it will not receive an additional MembershipInitializeEvent. So this is a once only event.
