Method Detail

getDistributedObjectName

protected String getDistributedObjectName()

getNameAsPartitionAwareData

protected Data getNameAsPartitionAwareData()

getPartitionKey

public String getPartitionKey()

Description copied from interface: DistributedObject

Returns the key of the partition that this DistributedObject is assigned to. The returned value only has meaning for a non-partitioned data structure like an IAtomicLong. For a partitioned data structure like an IMap, the returned value will not be null, but otherwise undefined.

Specified by:

getPartitionKey in interface DistributedObject

Returns:

the partition key.

destroy

public final void destroy()

Description copied from interface: DistributedObject

Destroys this object cluster-wide. Clears and releases all resources for this object.

Specified by:

destroy in interface DistributedObject

toData

protected final Data toData(Object object)

invokeOnPartition

protected final <E> InternalCompletableFuture<E> invokeOnPartition(Operation operation)

getPartitionId

protected final int getPartitionId(Data key)

preDestroy

protected boolean preDestroy()

postDestroy

protected void postDestroy()

getNodeEngine

public final NodeEngine getNodeEngine()

Gets the node engine.

Returns:

the node engine

Throws:

HazelcastInstanceNotActiveException - if NodeEngine not active or DistributedObject destroyed.

throwNotActiveException

protected void throwNotActiveException()

getService

public final S getService()

Gets the Service of this AbstractDistributedObject.

Returns:

the Service of this AbstractDistributedObject

Throws:

HazelcastInstanceNotActiveException - if object is destroyed or HazelcastInstance shutdown.

getOperationService

public final OperationService getOperationService()

Gets the OperationService.

Returns:

the OperationService.

Throws:

HazelcastInstanceNotActiveException - if object is destroyed or HazelcastInstance shutdown.

getServiceName

public abstract String getServiceName()

Description copied from interface: DistributedObject

Returns the service name for this object.

Specified by:

getServiceName in interface DistributedObject

Returns:

the service name for this object.

invalidate

public final void invalidate()

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString()

Overrides:

toString in class Object
