Method Detail

getResponse

public final Object getResponse()

Description copied from class: Operation

Called if and only if Operation.returnsResponse() returned true, shortly after Operation.run() returns.

Overrides:

getResponse in class Operation

getLockStore

protected final LockStoreImpl getLockStore()

getSyncBackupCount

public final int getSyncBackupCount()

getAsyncBackupCount

public final int getAsyncBackupCount()

setAsyncBackup

public final void setAsyncBackup(boolean asyncBackup)

onSetCallId

protected void onSetCallId(long callId)

Description copied from class: Operation

Called every time a new callId is set on the operation. A new callId is set before initial invocation and before every invocation retry.

By default this is a no-op method. Operation implementations which want to get notified on callId changes can override it.

For example an operation can distinguish the first invocation and invocation retries by keeping the initial callId.

Overrides:

onSetCallId in class Operation

Parameters:

callId - the new call ID that was set on the operation

getReferenceCallId

protected final long getReferenceCallId()

setReferenceCallId

protected final void setReferenceCallId(long refCallId)

interceptLockOperation

protected final void interceptLockOperation()

getServiceName

public String getServiceName()

Overrides:

getServiceName in class Operation

getKey

public final Data getKey()

getName

public String getName()

Description copied from interface: NamedOperation

Returns the name of the distributed data structure.

Specified by:

getName in interface NamedOperation

Returns:

String name of the distributed data structure.

getServiceNamespace

public ServiceNamespace getServiceNamespace()

Description copied from interface: ServiceNamespaceAware

Returns the ServiceNamespace which this object belongs to.

Specified by:

getServiceNamespace in interface ServiceNamespaceAware

Returns:

service namespace

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

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.
