Class Int7uOSQVectorScorerSupplier.DotProductSupplier

java.lang.Object

org.elasticsearch.simdvec.internal.Int7uOSQVectorScorerSupplier

org.elasticsearch.simdvec.internal.Int7uOSQVectorScorerSupplier.DotProductSupplier

All Implemented Interfaces:

org.apache.lucene.util.hnsw.RandomVectorScorerSupplier

Enclosing class:

Int7uOSQVectorScorerSupplier

public static final class Int7uOSQVectorScorerSupplier.DotProductSupplier
extends Int7uOSQVectorScorerSupplier

DotProductSupplier relies on preview features of the Java platform:

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

Programs can only use DotProductSupplier when preview features are enabled.

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