Examples of ISourceViewer

org.eclipse.jface.text.source.ISourceViewer
In addition to the text viewer functionality a source viewer supports:
- visual annotations based on an annotation model
- visual range indication
- management of text viewer add-ons
- explicit configuration
It is assumed that range indication and visual annotations are shown inside the same presentation area. There are no assumptions about whether this area is different from the viewer's text widget.
As the visibility of visual annotations can dynamically be changed, it is assumed that the annotation presentation area can dynamically be hidden if it is different from the text widget.
In order to provide backward compatibility for clients of ISourceViewer, extension interfaces are used as a means of evolution. The following extension interfaces exist:
- {@link org.eclipse.jface.text.source.ISourceViewerExtension} since version 2.1introducing the concept of an annotation overview.
- {@link org.eclipse.jface.text.source.ISourceViewerExtension2} since version 3.0allowing source viewers to roll back a previously performed configuration and allows access to the viewer's visual annotation model.
- {@link org.eclipse.jface.text.source.ISourceViewerExtension3} since version 3.2introducing the concept of a quick assist assistant and providing access to the quick assist invocation context as well as the current annotation hover.
- {@link org.eclipse.jface.text.source.ISourceViewerExtension4} since version 3.4introducing API to access a minimal set of content assistant APIs.
Clients may implement this interface and its extension interfaces or use the default implementation provided by {@link org.eclipse.jface.text.source.SourceViewer}.
