Interface Summary

Interface	Description
BaseMap<K,V>	Base interface for Hazelcast distributed maps.
BaseMultiMap<K,V>	Base interface for Hazelcast distributed multi-maps.
BaseQueue<E>	Base interface for Hazelcast distributed queues.
Client	Client interface allows to get information about a connected clients socket address, type and uuid.
ClientListener	ClientListener allows to get notified when a Client is connected to or disconnected from cluster.
ClientService	ClientService allows to query connected Clients and attach/detach ClientListeners to listen connection events.
Cluster	Hazelcast cluster interface.
DistributedObject	Base interface for all distributed objects.
DistributedObjectListener	DistributedObjectListener allows to get notified when a DistributedObject is created or destroyed cluster-wide.
EntryListener<K,V>	Map Entry listener to get notified when a map entry is added, removed, updated or evicted.
EntryView<K,V>	EntryView represents a readonly view of a map entry.
ExecutionCallback<V>	ExecutionCallback allows to asynchronously get notified when the execution is completed, either successfully or with error.
HazelcastInstance	Hazelcast instance.
HazelcastInstanceAware	Used to get HazelcastInstance reference when submitting a Runnable/Callable using Hazelcast ExecutorService.
IAtomicLong	IAtomicLong is a redundant and highly available distributed alternative to the java.util.concurrent.atomic.AtomicLong.
ICollection<E>	Concurrent, distributed, partitioned, listenable collection.
ICondition	Distributed implementation of Condition.
ICountDownLatch	ICountDownLatch is a backed-up distributed alternative to the java.util.concurrent.CountDownLatch.
IdGenerator	Cluster-wide unique id generator.
IExecutorService	Distributed implementation of ExecutorService.
IList<E>	Concurrent, distributed implementation of List
ILock	Distributed implementation of Lock.
IMap<K,V>	Concurrent, distributed, observable and queryable map.
InitialMembershipListener	The InitializingMembershipListener is a MembershipListener that will first receives a InitialMembershipEvent when it is registered so it immediately knows which members are available.
IQueue<E>	Concurrent, blocking, distributed, observable queue.
ISemaphore	ISemaphore is a backed-up distributed alternative to the Semaphore.
ISet<E>	Concurrent, distributed implementation of Set This class is not a general-purpose Set implementation! While this class implements the Set interface, it intentionally violates Set's general contract, which mandates the use of the equals method when comparing objects.
ItemListener<E>	Item listener for IQueue, ISet and IList
ITopic<E>	Hazelcast provides distribution mechanism for publishing messages that are delivered to multiple subscribers which is also known as publish/subscribe (pub/sub) messaging model.
LifecycleListener	Listener object for lisntening lifecycle events of hazelcast instance
LifecycleService	LifecycleService allows you to shutdown, terminate and listen to LifecycleEvent's on HazelcastInstance.
ManagedContext	Container managed context, such as Spring, Guice and etc.
MapLoader<K,V>	Hazelcast distributed map implementation is an in-memory data store but it can be backed by any type of data store such as RDBMS, OODBMS, or simply a file based data store.
MapLoaderLifecycleSupport	Provides Lifecycle support for the implementing MapLoader class.
MapStore<K,V>	Hazelcast distributed map implementation is an in-memory data store but it can be backed by any type of data store such as RDBMS, OODBMS, NOSQL or simply a file based data store.
MapStoreFactory<K,V>	Factory for MapLoader or MapStore instances, specifiable in MapStoreConfig.
Member	Cluster member interface.
MembershipListener	Cluster membership listener.
MessageListener<E>	Message listener for ITopic.
MigrationListener	MigrationListener allows to listen partition migration events.
MultiExecutionCallback	MultiExecutionCallback allows to get notified when an execution is completed on each member which task is submitted to.
MultiMap<K,V>	A specialized map whose keys can be associated with multiple values.
Partition	Virtual partition instance.
PartitionAware<T>	PartitionAware allows implementing keys to be located on the same member or implementing tasks to be executed on PartitionAware.getPartitionKey()'s owner member.
PartitioningStrategy<K>	PartitioningStrategy allows keys to be located on the same member This makes related data to be stored in the same location.
PartitionService	PartitionService allows to query Partitions and attach/detach MigrationListeners to listen partition migration events.
QueueStore<T>	QueueStore makes a queue backed by a central data store; such as database, disk etc.
QueueStoreFactory<T>
TransactionalList<E>	Transactional implementation of IList.
TransactionalMap<K,V>	Transactional implementation of BaseMap.
TransactionalMultiMap<K,V>	Transactional implementation of BaseMultiMap.
TransactionalQueue<E>	Transactional implementation of BaseQueue.
TransactionalSet<E>	Transactional implementation of ISet.

EntryAdapter<K,V>	Adapter for EntryListener.
EntryEvent<K,V>	Map Entry event.
Hazelcast	Factory for HazelcastInstance's, a node in a cluster.
InitialMembershipEvent	A event that is send when a InitialMembershipListener registers itself on a Cluster.
ItemEvent<E>	Map Item event.
LifecycleEvent	Lifecycle event fired when HazelcastInstance's state changes.
MapStoreAdapter<K,V>	Adapter for MapStore.
MembershipEvent	Membership event fired when a new member is added to the cluster and/or when a member leaves the cluster.
