Method Detail

replicate

protected ICompletableFuture replicate(RaftNode raftNode)

Specified by:

replicate in class RaftReplicateOp

isRetryableOnIndeterminateOperationState

public boolean isRetryableOnIndeterminateOperationState()

Description copied from interface: IndeterminateOperationStateAware

Returns true if duplicate commit of the operation is equivalent to committing it only once.

Specified by:

isRetryableOnIndeterminateOperationState in interface IndeterminateOperationStateAware

getFactoryId

public int getFactoryId()

Description copied from interface: IdentifiedDataSerializable

Returns DataSerializableFactory factory ID for this class.

Specified by:

getFactoryId in interface IdentifiedDataSerializable

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

writeInternal

protected void writeInternal(ObjectDataOutput out)
                      throws IOException

Overrides:

writeInternal in class RaftReplicateOp

Throws:

IOException

readInternal

protected void readInternal(ObjectDataInput in)
                     throws IOException

Overrides:

readInternal in class RaftReplicateOp

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 to always 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 RaftReplicateOp

Parameters:

sb - the StringBuilder to add the debug info to.
