Method Detail

serializeToMigrate

byte[] serializeToMigrate(String objectId)

Prepares a cloud object for migration. After successful preparation the cloud object is serialized and returned to the caller as byte array.

Parameters:

objectId - The cloud object to prepare/migrate

Returns:

The serialized cloud object as byte array

deployMigratedCloudObject

void deployMigratedCloudObject(String objectId,
                             String classname,
                             byte[] serializedCloudObject)

Deploys a previously serialized cloud object. Deployment includes deserialization, initialization, preparation and registration of the cloud object's id at the cloud host

Parameters:

objectId - The id of the cloud object

classname - Classname of the serialized cloud object

serializedCloudObject - The serialized cloud object

removeCloudObject

void removeCloudObject(String id)

Destroys the remaining cloud object on the source host after a successful migration. This method is basically only a wrapper for IJCloudScaleServer.destroyCloudObject(String) to prevent ObjectLifecycleEventAspect from issuing a ObjectDestroyedEvent.

Parameters:

id - The id of the migrated cloud object
