Examples of org.eclipse.jdt.core.dom.WildcardType

org.eclipse.jdt.core.dom.WildcardType
Type node for a wildcard type (added in JLS3 API).
```
 WildcardType: { Annotation } ? [ ( extends | super) Type ] 
```
Not all node arrangements will represent legal Java constructs. In particular, it is nonsense if a wildcard type node appears anywhere other than as an argument of a ParameterizedType node.
