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()

onExecutionFailure

public void onExecutionFailure(Throwable e)

Description copied from class: Operation

Called when an Exception/Error is thrown during operation execution.

By default this method does nothing. Operation implementations can override this behaviour according to their needs.

This method is called on node & thread that's executing the operation.

Overrides:

onExecutionFailure in class Operation

Parameters:

e - Exception/Error thrown during operation execution

validatesTarget

public boolean validatesTarget()

Overrides:

validatesTarget 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

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.

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

setTarget

public void setTarget(Address address)

Description copied from interface: TargetAware

Provides the designated target member address to which the operation will be sent.

• This method is invoked on the implementing object before the operation is serialized and sent over the network
• When an operation is retried, the target may be re-evaluated (eg a partition operation may target a different member after a topology change). setTarget will be invoked on each retry with the current target member's Address as argument
• When an operation is executed on the local member, the local member's address is provided as target address

Specified by:

setTarget in interface TargetAware

Parameters:

address - target member's address
