Class AbstractCRDTReplicationOperation<T extends IdentifiedDataSerializable>

java.lang.Object

com.hazelcast.spi.Operation

com.hazelcast.crdt.AbstractCRDTReplicationOperation<T>

Type Parameters:

T - the CRDT type

All Implemented Interfaces:

MigrationCycleOperation, DataSerializable, IdentifiedDataSerializable, AllowedDuringPassiveState, UrgentSystemOperation

Direct Known Subclasses:

PNCounterReplicationOperation

public abstract class AbstractCRDTReplicationOperation<T extends IdentifiedDataSerializable>
extends Operation
implements IdentifiedDataSerializable, MigrationCycleOperation

Base class for CRDT replication operations. It supports replicating a map of IdentifiedDataSerializable values. In the case of CRDT replication, this will be a map from map name to CRDT state. Each concrete implementation of this class should be responsible for a single CRDT type and the replication map should only contain CRDT states for this CRDT type.

Constructor Detail

AbstractCRDTReplicationOperation

protected AbstractCRDTReplicationOperation()

AbstractCRDTReplicationOperation

public AbstractCRDTReplicationOperation(Map<String,T> replicationData)

Constructs the replication operation.

Parameters:

replicationData - the map of CRDT states to replicate

Method Detail

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

See Also:

Operation.call()

afterRun

public void afterRun()
              throws Exception

Description copied from class: Operation

Is executed called after Operation.run() or Operation.call() method completes normally and the operation is not blocked, see CallStatus.WAIT. Runs after backups, before wait-notify.

Overrides:

afterRun in class Operation

Throws:

Exception

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

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
