Method Detail

run

public void run()

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

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 QueueOperation

Throws:

Exception

getFactoryId

public int getFactoryId()

Description copied from interface: IdentifiedDataSerializable

Returns DataSerializableFactory factory ID for this class.

Specified by:

getFactoryId in interface IdentifiedDataSerializable

Overrides:

getFactoryId in class QueueOperation

Returns:

factory ID

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
