```
public class DataFeatures
extends Object
```
Class with constants for possible data features defined in the a Data Feature Ontology. Actual integers are random and should not be used directly.
To test whether a IChemFormat supports a certain feature, the following code can be used:
```
 int features = new XYZFormat().getSupportedDataFeatures();
 boolean has3DCoords = (features & HAS_3D_COORDINATES) == HAS_3D_COORDINATES;
 
```
This list of constants matches the latest Blue Obelisk Data Features Ontology.
