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

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()

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

onInvocationException

public ExceptionAction onInvocationException(Throwable throwable)

Description copied from class: Operation

Called when an Exception/Error is thrown during an invocation. Invocation process will continue, it will retry or fail according to returned ExceptionAction.

This method is called on caller side of the invocation.

Overrides:

onInvocationException in class Operation

Parameters:

throwable - Exception/Error thrown during invocation

Returns:

ExceptionAction

getServiceName

public String getServiceName()

Overrides:

getServiceName in class Operation

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

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

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
