Constructor Detail

IdGeneratorProxy

public IdGeneratorProxy(IAtomicLong blockGenerator,
                        String name,
                        NodeEngine nodeEngine,
                        IdGeneratorService service)

Method Detail

init

public boolean init(long id)

Description copied from interface: IdGenerator

Tries to initialize this IdGenerator instance with the given ID.

The next generated ID will be 1 greater than the supplied ID.

Specified by:

init in interface IdGenerator

Returns:

true if initialization succeeded, false otherwise.

newId

public long newId()

Description copied from interface: IdGenerator

Generates and returns a cluster-wide unique ID.

Specified by:

newId in interface IdGenerator

Returns:

new cluster-wide unique ID

getName

public String getName()

Description copied from interface: DistributedObject

Returns the unique name for this DistributedObject. The returned value will never be null. The suggested way for getting name is retrieving it through DistributedObjectUtil.getName(DistributedObject) because this might be also a PrefixedDistributedObject.

Specified by:

getName in interface DistributedObject

Returns:

the unique name for this object.

getServiceName

public String getServiceName()

Description copied from interface: DistributedObject

Returns the service name for this object.

Specified by:

getServiceName in interface DistributedObject

Specified by:

getServiceName in class AbstractDistributedObject<IdGeneratorService>

Returns:

the service name for this object.

postDestroy

protected void postDestroy()

Overrides:

postDestroy in class AbstractDistributedObject<IdGeneratorService>
