Examples of org.eclipse.jface.text.source.Annotation

org.eclipse.jface.text.source.Annotation
Annotation managed by an {@link org.eclipse.jface.text.source.IAnnotationModel}.
Annotations are typed, can have an associated text and can be marked as persistent and deleted. Annotations which are not explicitly initialized with an annotation type are of type "org.eclipse.text.annotation.unknown".
