Method Detail

beforeRun

public void beforeRun()
               throws Exception

Description copied from class: Operation

The beforeRun is called before either the Operation.run() or the Operation.call() method is called. runs before wait-support

Overrides:

beforeRun in class Operation

Throws:

Exception

shouldWait

public boolean shouldWait()

Specified by:

shouldWait in interface BlockingOperation

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()

getWaitKey

public WaitNotifyKey getWaitKey()

Specified by:

getWaitKey in interface BlockingOperation

onWaitExpire

public void onWaitExpire()

Specified by:

onWaitExpire in interface BlockingOperation

getResponse

public Data 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

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

writeInternal

protected void writeInternal(ObjectDataOutput out)
                      throws IOException

Overrides:

writeInternal in class AbstractRingBufferOperation

Throws:

IOException

readInternal

protected void readInternal(ObjectDataInput in)
                     throws IOException

Overrides:

readInternal in class AbstractRingBufferOperation

Throws:

IOException
