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

java.lang.Object
- elki.evaluation.scores.adapter.OutlierScoreAdapter

All Implemented Interfaces:

elki.evaluation.scores.ScoreEvaluation.Adapter, elki.utilities.datastructures.iterator.Iter
```
public class OutlierScoreAdapter
extends java.lang.Object
implements elki.evaluation.scores.ScoreEvaluation.Adapter
```
This adapter can be used for an arbitrary collection of Integers, and uses that id1.compareTo(id2) != 0 for id1 != id2 to satisfy the comparability.
Note that of course, no id should occur more than once.
The ROC values would be incorrect then anyway!

Since:

0.7.0
