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

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

Constructs a hazelcastClient with given ClientConfig.

Note: ClientConfig will be copied.

Member Function Documentation

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

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

Returns: configuration of this Hazelcast client.

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

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

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

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

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

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.

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

template<typename E >

IList<E> hazelcast::client::HazelcastClient::getList ( const std::string & name )

inline

Returns: distributed list instance with the specified name

template<typename K , typename V >

IMap<K, V> hazelcast::client::HazelcastClient::getMap ( const std::string & name )

inline

Returns the distributed map instance with the specified name.

Template Parameters

K	key type
V	value type

Parameters

name	name of the distributed map

Returns: distributed map instance with the specified name

template<typename K , typename V >

MultiMap<K, V> hazelcast::client::HazelcastClient::getMultiMap ( const std::string & name )

inline

Returns the distributed multimap instance with the specified name.

Parameters

name	name of the distributed multimap

Returns: distributed multimap instance with the specified name

template<typename E >

IQueue<E> hazelcast::client::HazelcastClient::getQueue ( const std::string & name )

inline

Returns the distributed queue instance with the specified name and entry type E.

Parameters

name	name of the distributed queue

Returns: distributed queue instance with the specified name

template<typename E >

ISet<E> hazelcast::client::HazelcastClient::getSet ( const std::string & name )

inline

Returns the distributed set instance with the specified name and entry type E.

Set is ordered unique set of entries. similar to std::set

Parameters

name	name of the distributed set

Returns: distributed set instance with the specified name

template<typename E >

ITopic<E> hazelcast::client::HazelcastClient::getTopic ( const std::string & name )

inline

Returns the distributed topic instance with the specified name and entry type E.

Parameters

name	name of the distributed topic

Returns: distributed topic instance with the specified name

TransactionContext hazelcast::client::HazelcastClient::newTransactionContext ( )

Creates a new TransactionContext associated with the current thread using default options.

Returns: new TransactionContext

TransactionContext hazelcast::client::HazelcastClient::newTransactionContext ( const TransactionOptions & options )

Creates a new TransactionContext associated with the current thread with given options.

Parameters

options options for this transaction

Returns: new TransactionContext

bool hazelcast::client::HazelcastClient::removeLifecycleListener ( LifecycleListener * lifecycleListener )

Remove lifecycle listener.

Parameters

lifecycleListener

Returns: true if removed successfully
