VotesCollectorDataCache (Fiji Javadocs 0-SNAPSHOT API)

java.lang.Object
- hr.irb.fastRandomForest.VotesCollectorDataCache

All Implemented Interfaces:

Callable<Double>
```
public class VotesCollectorDataCache
extends Object
implements Callable<Double>
```
Used to retrieve the out-of-bag vote of an FastRandomForest classifier for a single instance from a DataCache the forest was trained on. New in 0.99. Used for OOB error calculation and feature importances.
In classification, does not return the class distribution, but only the class index of the dominant class.

Implements callable so it can be run in multiple threads.
