Examples of com.google.dart.engine.ast.Annotation

com.google.dart.engine.ast.Annotation
Instances of the class {@code Annotation} represent an annotation that can be associated with anAST node.
```
 metadata ::= annotation annotation ::= '@'  {@link Identifier qualified} ('.' {@link SimpleIdentifier identifier})?  {@link ArgumentList arguments}? 
```
