LinearScanPrimitiveDistanceRangeByObject (ELKI: Environment for DeveLoping KDD-Applications Supported by Index-Structures)

java.lang.Object
- elki.database.query.range.LinearScanPrimitiveDistanceRangeByObject<O>

Type Parameters:

O - relation object type

All Implemented Interfaces:

LinearScanQuery, RangeSearcher<O>
```
public class LinearScanPrimitiveDistanceRangeByObject<O>
extends java.lang.Object
implements RangeSearcher<O>, LinearScanQuery
```
Default linear scan range query class.
Subtle optimization: for primitive distances, retrieve the query object only once from the relation.

Since:

0.4.0
