public interface UncertainObject
extends SpatialComparable, FeatureVector<java.lang.Double>
```
Interface for uncertain objects. Uncertain objects must provide a bounding box in this model, and have an option to randomly sample from the data. TODO: Eventually allow float precision, too.

Since:

0.7.0
