Object
- EqualAreaListVisitor

All Implemented Interfaces:

FeatureVisitor, FeatureCalc
```
public class EqualAreaListVisitor
extends Object
implements FeatureCalc
```
Obtains the data needed for a Equal Area operation (classification of features into classes each roughly having the same area).
The result contains an array of lists with the expression values in each.
