Method Detail

run

public void run()
         throws Exception

Overrides:

run in class Operation

Throws:

Exception

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

getResponse

public Object getResponse()

Description copied from class: Operation

Called if and only if Operation.returnsResponse() returned true, shortly after Operation.run() returns.

Overrides:

getResponse in class Operation

validatesTarget

public boolean validatesTarget()

Overrides:

validatesTarget in class Operation

getServiceName

public String getServiceName()

Overrides:

getServiceName in class Operation

logError

public void logError(Throwable e)

Description copied from class: Operation

Logs Exception/Error thrown during operation execution. Operation implementations can override this behaviour due 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

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 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 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

getFactoryId

public final int getFactoryId()

Description copied from interface: IdentifiedDataSerializable

Returns DataSerializableFactory factory ID for this class.

Specified by:

getFactoryId in interface IdentifiedDataSerializable

Returns:

factory ID
