Class Int7SQVectorScorerSupplier

java.lang.Object

org.elasticsearch.simdvec.internal.Int7SQVectorScorerSupplier

All Implemented Interfaces:

org.apache.lucene.util.hnsw.RandomVectorScorerSupplier, QuantizedByteVectorValuesAccess

Direct Known Subclasses:

Int7SQVectorScorerSupplier.DotProductSupplier, Int7SQVectorScorerSupplier.EuclideanSupplier, Int7SQVectorScorerSupplier.MaxInnerProductSupplier

public abstract sealed class Int7SQVectorScorerSupplier
extends Object
implements org.apache.lucene.util.hnsw.RandomVectorScorerSupplier, QuantizedByteVectorValuesAccess
permits Int7SQVectorScorerSupplier.EuclideanSupplier, Int7SQVectorScorerSupplier.DotProductSupplier, Int7SQVectorScorerSupplier.MaxInnerProductSupplier

Int7SQVectorScorerSupplier relies on preview features of the Java platform:

• Int7SQVectorScorerSupplier refers to one or more preview APIs: MemorySegment.

Programs can only use Int7SQVectorScorerSupplier when preview features are enabled.

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