ReplicaFragmentMigrationState

public ReplicaFragmentMigrationState(Map<ServiceNamespace,long[]> namespaces,
                                     Collection<Operation> migrationOperations)

Method Detail

getNamespaceVersionMap

public Map<ServiceNamespace,long[]> getNamespaceVersionMap()

getMigrationOperations

public Collection<Operation> getMigrationOperations()

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

getClassId

public int getClassId()

Description copied from interface: IdentifiedDataSerializable

Returns type identifier for this class. It should be unique per DataSerializableFactory.

Specified by:

getClassId 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

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

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.

setTarget

public void setTarget(Address address)

Description copied from interface: TargetAware

Provides the designated target member address to which the operation will be sent.

• This method is invoked on the implementing object before the operation is serialized and sent over the network
• When an operation is retried, the target may be re-evaluated (eg a partition operation may target a different member after a topology change). setTarget will be invoked on each retry with the current target member's Address as argument
• When an operation is executed on the local member, the local member's address is provided as target address

Specified by:

setTarget in interface TargetAware

Parameters:

address - target member's address
