Method Detail

readProperty

long[][] readProperty(long[] relationshipReferences,
                      org.neo4j.gds.compat.PropertyReference[] propertyReferences,
                      int numberOfReferences,
                      int[] propertyKeyIds,
                      double[] defaultValues,
                      org.neo4j.gds.core.Aggregation[] aggregations,
                      boolean atLeastOnePropertyToLoad)

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

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
