    Description copied from class: ExpressionAbstract
    
    Subclass should override, default implementation returns null.
    
    Specified by:
    
    evaluate in interface Expression
    
    Overrides:
    
    evaluate in class FunctionExpressionImpl
    
    Returns:
    
    default implementation returns null
  - invert
```
public ReferencedEnvelope invert(ReferencedEnvelope renderingEnvelope)
```
    Returns an translated rendering envelope if the offsets are not using feature attributes. If the offsets are feature dependent the user will have to expand the rendering area via the renderer buffer parameter
    
    Specified by:
    
    invert in interface GeometryTransformation
