Class GenericOperation

java.lang.Object

com.hazelcast.spi.Operation

com.hazelcast.ringbuffer.impl.operations.AbstractRingBufferOperation

com.hazelcast.ringbuffer.impl.operations.GenericOperation

All Implemented Interfaces:

DataSerializable, IdentifiedDataSerializable, AllowedDuringPassiveState, NamedOperation, PartitionAwareOperation, ReadonlyOperation, ServiceNamespaceAware

public class GenericOperation
extends AbstractRingBufferOperation
implements ReadonlyOperation

Ring buffer operations which don't need to send any parameters and which can be determined by only sending the operation type which is a byte of information. Typically these are read operations and/or getters.

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()

getResponse

public Long 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

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

writeInternal

protected void writeInternal(ObjectDataOutput out)
                      throws IOException

Overrides:

writeInternal in class AbstractRingBufferOperation

Throws:

IOException

readInternal

protected void readInternal(ObjectDataInput in)
                     throws IOException

Overrides:

readInternal in class AbstractRingBufferOperation

Throws:

IOException
