Examples of org.eclipse.jface.text.source.projection.ProjectionAnnotation

org.eclipse.jface.text.source.projection.ProjectionAnnotation
Annotation used to represent the projection of a master document onto a {@link org.eclipse.jface.text.projection.ProjectionDocument}. A projection annotation can be either expanded or collapsed. If expanded it corresponds to a segment of the projection document. If collapsed, it represents a region of the master document that does not have a corresponding segment in the projection document.
Clients may subclass or use as is.
