DuplicatingStyleVisitor (Geotools modules 21.0 API)

Object
- DuplicatingStyleVisitor

All Implemented Interfaces:

StyleVisitor

Direct Known Subclasses:

ChannelSelectionUpdateStyleVisitor, RescaleStyleVisitor, UomRescaleStyleVisitor
```
public class DuplicatingStyleVisitor
extends Object
implements StyleVisitor
```
Creates a deep copy of a Style, this class is *NOT THREAD SAFE*.
This class makes use of an internal stack to story the copied result, retrieve with a call to getCopy() after visiting:
```
 DuplicatingStyleVisitor copyStyle = new DuplicatingStyleVisitor();
 rule.accepts( copyStyle );
 Rule rule = (Rule) copyStyle.getCopy();
 
```
This class is often used as a base for an anoymous subclass where a style transformation is needed (such as removing PointSymbolizers or changing the scale - see RescaleStyleVisitor for an example).
