Object
- ExpressionAbstract
- - DefaultExpression
  - - FunctionExpressionImpl
    - - GeometryFunction

All Implemented Interfaces:

Expression, Function, VolatileFunction, FunctionExpression, Factory
```
public class GeometryFunction
extends FunctionExpressionImpl
implements VolatileFunction
```
Function the returns the default geometry of a feature, or null if there is none, or it's not a JTS geometry
