Class Int7SQVectorScorerSupplier.MaxInnerProductSupplier

java.lang.Object

org.elasticsearch.simdvec.internal.Int7SQVectorScorerSupplier

org.elasticsearch.simdvec.internal.Int7SQVectorScorerSupplier.MaxInnerProductSupplier

All Implemented Interfaces:

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

Enclosing class:

Int7SQVectorScorerSupplier

public static final class Int7SQVectorScorerSupplier.MaxInnerProductSupplier
extends Int7SQVectorScorerSupplier

MaxInnerProductSupplier relies on preview features of the Java platform:
