Interface IAnnotationManager

public interface IAnnotationManager

This interface manages the selection cycle for AnnotationComponents. AnnotationComponents can be programmatically selected and deselected with selectAnnotationComponent(AnnotationComponent) and deselectAnnotationComponent(AnnotationComponent).

Listeners can register with this class with addSelectionListener(IAnnotSelectionListener).

An implementation of this class can be obtained from a PDFViewerBean with PDFViewerBean.getAnnotationManager().
