public class ProjectionViewer extends SourceViewer implements ITextViewerExtension5
A projection source viewer is a source viewer which supports multiple visible regions which can dynamically be changed.A projection source viewer uses a
ProjectionDocumentManagerfor the management of the visible document.NOTE: The
ProjectionVieweronly supports projections that cover full lines.This class should not be subclassed.
- Since:
- 3.0
- Restriction:
- This class is not intended to be subclassed by clients.
