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

org.eclipse.jdt.core.dom.SingleMemberAnnotation
Single member annotation node (added in JLS3 API). The single member annotation "@foo(bar)" is equivalent to the normal annotation "@foo(value=bar)".
```
 SingleMemberAnnotation: @ TypeName ( Expression  ) 
```
Within annotations, only certain kinds of expressions are meaningful, including other annotations.
@since 3.1 @noinstantiate This class is not intended to be instantiated by clients.
