Package elki.database.query.range

Class LinearScanPrimitiveSimilarityRangeByObject<O>

  • Type Parameters:
    O - relation object type
    All Implemented Interfaces:
    elki.database.query.LinearScanQuery, elki.database.query.range.RangeSearcher<O>
    public class LinearScanPrimitiveSimilarityRangeByObject<O>
extends java.lang.Object
implements elki.database.query.range.RangeSearcher<O>, elki.database.query.LinearScanQuery
    Default linear scan range query class.

    Subtle optimization: for primitive similarities, retrieve the query object only once from the relation.
