```
public class DatumParameters
extends java.lang.Object
```
Contains the parsed/computed parameter values which are used to create the datum and ellipsoid for a CoordinateReferenceSystem. This class also implements the policies for which parameters take precedence when multiple inconsistent ones are present.
