        Parameters:
        batch - relationship data
        batchLength - number of valid entries in the batch data
        propertyKeyIds - property key ids to load
        defaultValues - default weight for each property key
        aggregations - the aggregation for each property
        atLeastOnePropertyToLoad - true iff there is at least one value in propertyKeyIds that is not StatementConstants.NO_SUCH_PROPERTY_KEY (-1).
        Returns:
        list of property values per per relationship property id
