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

org.eclipse.jface.text.source.AnnotationModelEvent
Specification of changes applied to annotation models. The event carries the changed annotation model as well as added, removed, and modified annotations.
An event can be sealed. Afterwards it can not be modified. Thus, the normal process is that an empty event is created, filled with the changed information, and before it is sent to the listeners, the event is sealed. @see org.eclipse.jface.text.source.IAnnotationModel @see org.eclipse.jface.text.source.IAnnotationModelListenerExtension @since 2.0
