Method Detail

getResponse

public final Object getResponse()

Overrides:

getResponse in class AbstractOperation

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()

Description copied from class: Operation

This method is called every time a new callId is set to the operation. A new callId is set to an operation before initial invocation and before every invocation retry.

By default this is a no-op method. Operation implementations which are willing to get notified on callId changes can override this method. New callId can be accessed by calling Operation.getCallId().

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

Overrides:

onSetCallId in class Operation

setReferenceCallId

protected final void setReferenceCallId(long refCallId)

getReferenceCallId

protected final long getReferenceCallId()

getServiceName

public final String getServiceName()

Overrides:

getServiceName in class Operation

getKey

public final Data getKey()

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 AbstractOperation

Throws:

IOException

readInternal

protected void readInternal(ObjectDataInput in)
                     throws IOException

Overrides:

readInternal in class AbstractOperation

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 always to 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.
