Description copied from interface: RelationshipImporter.PropertyReader

Load the relationship properties for the given batch of relationships. Relationships are represented as two arrays from the RelationshipsBatchBuffer.

Specified by:

readProperty in interface RelationshipImporter.PropertyReader

Parameters:

relationshipReferences - relationship references (IDs)

propertyReferences - property references (IDs or References)

numberOfReferences - number of valid entries in the first two arrays

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 relationship property id
