Method Detail

run

public Object run(CPGroupId groupId,
                  long commitIndex)

Description copied from class: RaftOp

Contains actual Raft operation logic. State change represented by this operation should be applied and execution result should be returned to the caller.

Specified by:

run in class RaftOp

Parameters:

groupId - groupId of the specific Raft group

commitIndex - commitIndex of the log entry keeping this operation

Returns:

result of the operation execution

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

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

writeData

public void writeData(ObjectDataOutput out)
               throws IOException

Description copied from interface: DataSerializable

Writes object fields to output stream

Specified by:

writeData in interface DataSerializable

Overrides:

writeData in class AbstractAtomicRefOp

Parameters:

out - output

Throws:

IOException - if an I/O error occurs. In particular, an IOException may be thrown if the output stream has been closed.

readData

public void readData(ObjectDataInput in)
              throws IOException

Description copied from interface: DataSerializable

Reads fields from the input stream

Specified by:

readData in interface DataSerializable

Overrides:

readData in class AbstractAtomicRefOp

Parameters:

in - input

Throws:

IOException - if an I/O error occurs. In particular, an IOException may be thrown if the input stream has been closed.
