Method Detail

getServiceName

public String getServiceName()

Overrides:

getServiceName in class Operation

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

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 Operation

Throws:

Exception

prepareForNextCleanup

protected void prepareForNextCleanup()

returnsResponse

public boolean returnsResponse()

Description copied from class: Operation

Method is intended to be subclassed. If it returns true, Operation.getResponse() will be called right after Operation.run() method. If it returns false, Operation.sendResponse(Object) must be called later to finish the operation.

In other words, true is for synchronous operation and false is for asynchronous one.

Default implementation is synchronous operation (true).

Overrides:

returnsResponse in class Operation

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.
