Class ProjectionAnnotation

  • All Implemented Interfaces:

    public class ProjectionAnnotation
    extends Annotation
    implements IAnnotationPresentation
    Annotation used to represent the projection of a master document onto a ProjectionDocument. A projection annotation can be either expanded or collapsed.
