- Method Detail
  - startLogRecoveryBatch
```
void startLogRecoveryBatch(int maxBatchSize)
```
    This method is called during recovery at the start of a batch of state entries. Derived classes should perform any initialization needed to start a batch.
    
    Parameters:
    
    maxBatchSize - the maximum batch size.
  - appendRecoveredLogEntry
```
void appendRecoveredLogEntry(Payload data)
```
    This method is called during recovery to append state data to the current batch. This method is called 1 or more times after startLogRecoveryBatch(int).
    
    Parameters:
    
    data - the state data
  - applyRecoverySnapshot
```
void applyRecoverySnapshot(Snapshot.State snapshotState)
```
    This method is called during recovery to reconstruct the state of the actor.
    
    Parameters:
    
    snapshotState - A snapshot of the state of the actor
  - applyCurrentLogRecoveryBatch
```
void applyCurrentLogRecoveryBatch()
```
    This method is called during recovery at the end of a batch to apply the current batched log entries. This method is called after appendRecoveredLogEntry(org.opendaylight.controller.cluster.raft.protobuff.client.messages.Payload).
  - getRestoreFromSnapshot
```
@Nullable Snapshot getRestoreFromSnapshot()
```
    Returns the snapshot to restore from on recovery.
