Examples of org.eclipse.jdt.core.IAnnotation

org.eclipse.jdt.core.IAnnotation
Represents an annotation on a package declaration, a type, a method, a field or a local variable in a compilation unit or a class file.
Annotations are obtained using {@link IAnnotatable#getAnnotation(String)}.
Note that annotations are not children of their declaring element. To get a list of the annotations use {@link IAnnotatable#getAnnotations()}.

This interface is not intended to be implemented or extended by clients.
