Class PartitionReplicaSyncResponse

java.lang.Object

com.hazelcast.spi.Operation

com.hazelcast.internal.partition.operation.PartitionReplicaSyncResponse

All Implemented Interfaces:

DataSerializable, IdentifiedDataSerializable, Versioned, BackupOperation, AllowedDuringPassiveState, TargetAware, PartitionAwareOperation, UrgentSystemOperation

public class PartitionReplicaSyncResponse
extends Operation
implements PartitionAwareOperation, BackupOperation, UrgentSystemOperation, AllowedDuringPassiveState, Versioned, TargetAware

The replica synchronization response sent from the partition owner to a replica. It will execute the received operation list if the replica index hasn't changed. If the current replica index is not the one sent by the partition owner, it will :

• fail all received operations
• cancel the current replica sync request
• if the node is still a replica it will reschedule the replica synchronization request
• if the node is not a replica anymore it will clear the replica versions for the partition

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()

returnsResponse

public boolean returnsResponse()

Description copied from class: Operation

Method is intended to be overridden. If it returns true, Operation.getResponse() will be called right after Operation.run() method. If it returns false, Operation.sendResponse(Object) must be called later to finish the operation.

In other words, true is for synchronous operation and false is for asynchronous one.

Default implementation is synchronous operation (true).

Overrides:

returnsResponse in class Operation

validatesTarget

public boolean validatesTarget()

Overrides:

validatesTarget in class Operation

getServiceName

public String getServiceName()

Overrides:

getServiceName in class Operation

onExecutionFailure

public void onExecutionFailure(Throwable e)

Description copied from class: Operation

Called when an Exception/Error is thrown during operation execution.

By default this method does nothing. Operation implementations can override this behaviour according to their needs.

This method is called on node & thread that's executing the operation.

Overrides:

onExecutionFailure in class Operation

Parameters:

e - Exception/Error thrown during operation execution

logError

public void logError(Throwable e)

Description copied from class: Operation

Logs Exception/Error thrown during operation execution. Operation implementations can override this behaviour according to their needs.

This method is called on node & thread that's executing the operation.

Overrides:

logError in class Operation

Parameters:

e - Exception/Error thrown during operation execution

setTarget

public void setTarget(Address address)

Description copied from interface: TargetAware

Provides the designated target member address to which the operation will be sent.

• This method is invoked on the implementing object before the operation is serialized and sent over the network
• When an operation is retried, the target may be re-evaluated (eg a partition operation may target a different member after a topology change). setTarget will be invoked on each retry with the current target member's Address as argument
• When an operation is executed on the local member, the local member's address is provided as target address

Specified by:

setTarget in interface TargetAware

Parameters:

address - target member's address

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

toString

protected void toString(StringBuilder sb)

Description copied from class: Operation

A template method allows for additional information to be passed into the Operation.toString() method. So an Operation subclass can override this method and add additional debugging content. The default implementation does nothing so one is not forced to provide an empty implementation. It is a good practice to always call the super.toString(stringBuffer) when implementing this method to make sure that the super class can inject content if needed.

Overrides:

toString in class Operation

Parameters:

sb - the StringBuilder to add the debug info to.

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

getFactoryId

public final int getFactoryId()

Description copied from interface: IdentifiedDataSerializable

Returns DataSerializableFactory factory ID for this class.

Specified by:

getFactoryId in interface IdentifiedDataSerializable

Returns:

factory ID
