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

org.eclipse.jdt.core.dom.MemberValuePair
Member value pair node (added in JLS3 API). Member value pairs appear in annotations.
```
 MemberValuePair: SimpleName = Expression 
```
Within annotations, only certain kinds of expressions are meaningful, including other annotations.
@see NormalAnnotation @since 3.1 @noinstantiate This class is not intended to be instantiated by clients.
