- Method Detail
  - startLoading
```
public void startLoading()
```
    Description copied from interface: RecordStore

  - setPreMigrationLoadedStatus
```
public void setPreMigrationLoadedStatus(boolean loaded)
```
    Description copied from interface: RecordStore
    
    Informs this recordStore about the loading status of the recordStore that this store is migrated from. If the 'predecessor' has been loaded this record store should trigger the load again. Will be taken into account only if invoked before the startLoading method. Otherwise has no effect.
    This method should be deleted when the map's lifecycle has been cleaned-up. Currently it's impossible to pass additional state when the record store is created, thus this this state has to be passed in post-creation setters which is cumbersome and error-prone.
