Class Operation

java.lang.Object
  com.hazelcast.spi.Operation

All Implemented Interfaces:

DataSerializable, RemotePropagatable<Operation>

Direct Known Subclasses:

AbstractOperation, AbstractReplicatedMapOperation, AtomicLongBaseOperation, AtomicReferenceBaseOperation, BeginTxBackupOperation, BroadcastTxRollbackOperation, CallableTaskOperation, CancellationOperation, CheckReplicaVersion, CollectionOperation, GetMapConfigOperation, IsReplicaVersionSync, KeyBasedMapOperation, MemberCallableTaskOperation, MultiMapOperation, PurgeTxBackupOperation, QueueOperation, RecoverTxnOperation, ReplicaSyncRequest, ReplicaSyncResponse, ReplicaSyncRetryResponse, ReplicateTxOperation, RollbackTxBackupOperation, ScriptExecutorOperation, ThreadDumpOperation, UpdateManagementCenterUrlOperation, UpdateMapConfigOperation

public abstract class Operation
extends Object
implements DataSerializable, RemotePropagatable<Operation>

An operation could be compared the a Runnable. So it contains logic that is going to be executed; this logic will be placed in the run() method.
