- loadMementoRawData
```
public BrooklynMementoRawData loadMementoRawData(RebindExceptionHandler exceptionHandler)
```
  Description copied from interface: BrooklynMementoPersister
  
  Loads raw data contents of the mementos.
  Some classes (esp deprecated ones) may return null here, meaning that the BrooklynMementoPersister.loadMementoManifest(BrooklynMementoRawData, RebindExceptionHandler) and BrooklynMementoPersister.loadMemento(BrooklynMementoRawData, LookupContext, RebindExceptionHandler) methods will populate the raw data via another source.

  Description copied from interface: BrooklynMementoPersister
  
  Loads minimal manifest information (almost entirely *not* deserialized). Implementations should load the raw data if BrooklynMementoRawData is not supplied, but callers are encouraged to supply that for optimal performance.
