ManagementPlaneSyncRecordPersisterToObjectStore (Apache Brooklyn)

java.lang.Object
- brooklyn.management.ha.ManagementPlaneSyncRecordPersisterToObjectStore

All Implemented Interfaces:

ManagementPlaneSyncRecordPersister
```
@Beta
public class ManagementPlaneSyncRecordPersisterToObjectStore
extends java.lang.Object
implements ManagementPlaneSyncRecordPersister
```
Structure of files is:
- plane/ - top-level directory
  - master - contains the id of the management-node that is currently master
  - change.log - log of changes made
  - nodes/ - sub-directory, containing one file per management-node
    - a9WiuVKp - file named after the management-node's id, containing the management node's current state
    - E1eDXQF3
All writes are done synchronously.
Since:

0.7.0

public ManagementPlaneSyncRecordPersisterToObjectStore(ManagementContext mgmt,
                                               PersistenceObjectStore objectStore,

```
    Parameters:
    mgmt - not used much at present but handy to ensure we know it so that obj store is prepared
    objectStore - the objectStore use to read/write management-plane data; this must have been PersistenceObjectStore.prepareForSharedUse(brooklyn.entity.rebind.persister.PersistMode, HighAvailabilityMode)
    classLoader - ClassLoader to use when deserializing data
