All Implemented Interfaces:

DataSerializable, IdentifiedDataSerializable, NamedOperation, PartitionAwareOperation, ServiceNamespaceAware

public class ReadAndResetAccumulatorOperation
extends MapOperation
implements PartitionAwareOperation

Reads all available items from the accumulator of the partition and resets it. This operation is used to retrieve the events which are buffered during the initial snapshot taking phase.

Method Detail

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()

returnsResponse

public boolean returnsResponse()

Description copied from class: Operation

Method is intended to be overridden. 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

writeInternal

protected void writeInternal(ObjectDataOutput out)
                      throws IOException

Overrides:

writeInternal in class AbstractNamedOperation

Throws:

IOException

readInternal

protected void readInternal(ObjectDataInput in)
                     throws IOException

Overrides:

readInternal in class AbstractNamedOperation

Throws:

IOException

getFactoryId

public int getFactoryId()

Description copied from interface: IdentifiedDataSerializable

Returns DataSerializableFactory factory ID for this class.

Specified by:

getFactoryId in interface IdentifiedDataSerializable

Overrides:

getFactoryId in class MapOperation

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
