NullDecoratorMapper (OpenSymphony SiteMesh 2.4.1 API)

java.lang.Object
- com.opensymphony.module.sitemesh.mapper.NullDecoratorMapper

All Implemented Interfaces:

DecoratorMapper
```
public class NullDecoratorMapper
extends Object
implements DecoratorMapper
```
The NullDecoratorMapper represents the top-level DecoratorMapper that is finally delegated to if no other DecoratorMapper has intervened. It is used so the parent property does not have to be checked by other DecoratorMappers (null object pattern).
