public CollectionMergeOperation(String name,
                                SplitBrainMergePolicy<Collection<Object>,SplitBrainMergeTypes.CollectionMergeTypes> mergePolicy,

CollectionMergeOperation

public CollectionMergeOperation()

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()

shouldBackup

public boolean shouldBackup()

Description copied from interface: BackupAwareOperation

Checks if a backup needs to be made.

If a call has not made any change, e.g. an AtomicLong increment with 0, no backup needs to be made.

Returns:

true if a backup needs to be made, false otherwise.

getBackupOperation

public Operation getBackupOperation()

Description copied from interface: BackupAwareOperation

Creates the BackupOperation responsible for making the backup.

Returns:

the created BackupOperation responsible for making the backup.

writeInternal

protected void writeInternal(ObjectDataOutput out)
                      throws IOException

Overrides:

writeInternal in class CollectionOperation

Throws:

IOException

readInternal

protected void readInternal(ObjectDataInput in)
                     throws IOException

Overrides:

readInternal in class CollectionOperation

Throws:

IOException

getId

public int getId()

Description copied from interface: IdentifiedDataSerializable

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

Returns:

type ID
