Method Detail

getResponse

public Object getResponse()

Overrides:

getResponse in class BaseMigrationOperation

run

public void run()
         throws Exception

Specified by:

run in class Operation

Throws:

Exception

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 due 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

writeInternal

protected void writeInternal(ObjectDataOutput out)
                      throws IOException

Overrides:

writeInternal in class BaseMigrationOperation

Throws:

IOException

readInternal

protected void readInternal(ObjectDataInput in)
                     throws IOException

Overrides:

readInternal in class BaseMigrationOperation

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 always to 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 BaseMigrationOperation

Parameters:

sb - the StringBuilder to add the debug info to.
