Class OnJoinCacheOperation

java.lang.Object

com.hazelcast.spi.Operation

com.hazelcast.cache.impl.operation.OnJoinCacheOperation

All Implemented Interfaces:

DataSerializable, IdentifiedDataSerializable

public class OnJoinCacheOperation
extends Operation
implements IdentifiedDataSerializable

Operation executed on joining members so they become aware of CacheConfigs dynamically created via CacheManager.createCache(String, Configuration). Depending on the cluster version, this operation is executed either as a post-join operation (when cluster version is < 3.9) or as a pre-join operation (since 3.9), to resolve a race between the CacheConfig becoming available in the joining member and creation of a ICache proxy.

addCacheConfig

public void addCacheConfig(CacheConfig cacheConfig)

getServiceName

public String getServiceName()

Overrides:

getServiceName in class Operation

run

public void run()
         throws Exception

Description copied from class: Operation

Runs the operation. Either the Operation.run() or Operation.call() method should be implemented; not both. Runs after wait-support, supposed to do actual operation

Overrides:

run in class Operation

Throws:

Exception

writeInternal

protected void writeInternal(ObjectDataOutput out)
                      throws IOException

Overrides:

writeInternal in class Operation

Throws:

IOException

readInternal

protected void readInternal(ObjectDataInput in)
                     throws IOException

Overrides:

readInternal in class Operation

Throws:

IOException

getFactoryId

public int getFactoryId()

Description copied from interface: IdentifiedDataSerializable

Returns DataSerializableFactory factory ID for this class.

Specified by:

getFactoryId in interface IdentifiedDataSerializable

Returns:

factory ID

getId

public int getId()

Description copied from interface: IdentifiedDataSerializable

Returns type identifier for this class. It should be unique per DataSerializableFactory.

Specified by:

getId in interface IdentifiedDataSerializable

Returns:

type ID
