Detailed Description

Hazelcast Client enables you to do all Hazelcast operations without being a member of the cluster.

It connects to one of the cluster members and delegates all cluster wide operations to it. When the connected cluster member dies, client will automatically switch to another live member.

Constructor & Destructor Documentation

◆ HazelcastClient()

hazelcast::client::HazelcastClient::HazelcastClient ( ClientConfig & config )

Constructs a hazelcastClient with given ClientConfig.

Note: ClientConfig will be copied.

Parameters

config client configuration to start the client with

Member Function Documentation

◆ addLifecycleListener()

void hazelcast::client::HazelcastClient::addLifecycleListener ( LifecycleListener * lifecycleListener )

Add listener to listen lifecycle events.

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.

Parameters

lifecycleListener Listener object

◆ getClientConfig()

ClientConfig & hazelcast::client::HazelcastClient::getClientConfig ( )

Returns: configuration of this Hazelcast client.

◆ getCluster()

Cluster & hazelcast::client::HazelcastClient::getCluster ( )

Returns the Cluster that connected Hazelcast instance is a part of.

Cluster interface allows you to add listener for membership events and learn more about the cluster.

Returns: cluster

◆ getDistributedObject()

template<typename T >

T hazelcast::client::HazelcastClient::getDistributedObject ( const std::string & name )

inline

Template Parameters

T	type of the distributed object

Parameters

name	name of the distributed object.

Returns: distributed object

◆ getFlakeIdGenerator()

FlakeIdGenerator hazelcast::client::HazelcastClient::getFlakeIdGenerator ( const std::string & name )

Returns a generator that creates a cluster-wide unique IDs.

Generated IDs are

long

primitive values and are k-ordered (roughly ordered). IDs are in the range from

0

to

Long.MAX_VALUE

.

The IDs contain timestamp component and a node ID component, which is assigned when the member joins the cluster. This allows the IDs to be ordered and unique without any coordination between members, which makes the generator safe even in split-brain scenario (for caveats, see here).

For more details and caveats, see class documentation for FlakeIdGenerator.

Note: this implementation doesn't share namespace with getIdGenerator(String). That is,

getIdGenerator("a")

is distinct from

getFlakeIdGenerator("a")

.

Parameters

name	name of the FlakeIdGenerator

Returns: FlakeIdGenerator for the given name

◆ getIAtomicLong()

IAtomicLong hazelcast::client::HazelcastClient::getIAtomicLong ( const std::string & name )

Creates cluster-wide atomic long.

Hazelcast IAtomicLong is distributed implementation of java.util.concurrent.atomic.AtomicLong.

Parameters

name	name of the IAtomicLong proxy

Returns: IAtomicLong proxy for the given name

◆ getICountDownLatch()

ICountDownLatch hazelcast::client::HazelcastClient::getICountDownLatch ( const std::string & name )

Creates cluster-wide CountDownLatch.

Hazelcast ICountDownLatch is distributed implementation of java.util.concurrent.CountDownLatch.

Parameters

name	name of the ICountDownLatch proxy

Returns: ICountDownLatch proxy for the given name

◆ getIdGenerator()

IdGenerator hazelcast::client::HazelcastClient::getIdGenerator ( const std::string & name )

Creates cluster-wide unique IDs.

Generated IDs are long type primitive values between 0 and LONG_MAX . Generated IDs are unique during the life cycle of the cluster. If the entire cluster is restarted, IDs start from 0 again.

Parameters

name	name of the IdGenerator

Returns: IdGenerator for the given name

◆ getILock()

ILock hazelcast::client::HazelcastClient::getILock ( const std::string & name )

Returns the distributed lock instance for the specified key object.

The specified object is considered to be the key for this lock. So keys are considered equals cluster-wide as long as they are serialized to the same byte array such as String, long, Integer.

Locks are fail-safe. If a member holds a lock and some of the members go down, cluster will keep your locks safe and available. Moreover, when a member leaves the cluster, all the locks acquired by this dead member will be removed so that these locks can be available for live members immediately.

 Lock lock = hazelcastInstance.getLock("PROCESS_LOCK");
 lock.lock();
 try {
   // process
 } finally {
   lock.unlock();
 }

Parameters

name	name of the lock instance

Returns: distributed lock instance for the specified name.

◆ getISemaphore()

ISemaphore hazelcast::client::HazelcastClient::getISemaphore ( const std::string & name )

Creates cluster-wide semaphore.

Hazelcast ISemaphore is distributed implementation of java.util.concurrent.Semaphore.

Parameters

name	name of the ISemaphore proxy

Returns: ISemaphore proxy for the given name

◆ getLifecycleService()

spi::LifecycleService & hazelcast::client::HazelcastClient::getLifecycleService ( )

Returns the lifecycle service for this instance.

LifecycleService allows you to shutdown this HazelcastInstance and listen for the lifecycle events.

Returns: the lifecycle service for this instance
