All Implemented Interfaces:

ResultRowMapperFactory

@Component
public class ArrayResultRowMapperFactory
extends Object
implements ResultRowMapperFactory

ResultRowMapperFactory that supports query results of type Object[]. The order of the array is defined by the order the paths are given to PathQueryBuilder.addPathToSelection(String...). Note: This mapper is only partially suited for to-many paths. When multiple to-many paths of the same entity are queried they cannot be referenced by array index, because null values are ignored. In addition nested to-many path values will be returned in one flattened array. MapResultRowMapperFactory is better suited for to many paths.
