Class BFloat16VectorScorerSupplier.EuclideanSupplier

java.lang.Object

org.elasticsearch.simdvec.internal.BFloat16VectorScorerSupplier

org.elasticsearch.simdvec.internal.BFloat16VectorScorerSupplier.EuclideanSupplier

All Implemented Interfaces:

org.apache.lucene.util.hnsw.RandomVectorScorerSupplier

Enclosing class:

BFloat16VectorScorerSupplier

public static final class BFloat16VectorScorerSupplier.EuclideanSupplier
extends BFloat16VectorScorerSupplier

EuclideanSupplier relies on preview features of the Java platform:

• EuclideanSupplier refers to one or more preview APIs: MemorySegment.

Programs can only use EuclideanSupplier when preview features are enabled.

Preview features may be removed in a future release, or upgraded to permanent features of the Java platform.
