Class SourceViewerConfiguration


java.lang.Object
  extended by 
org.eclipse.jface.text.source.SourceViewerConfiguration
Direct Known Subclasses:
TextSourceViewerConfiguration 
public class SourceViewerConfiguration

extends 
Object

This class bundles the configuration space of a source viewer. Instances of this class are passed to the configure method of ISourceViewer.

Each method in this class get as argument the source viewer for which it should provide a particular configuration setting such as a presentation reconciler. Based on its specific knowledge about the returned object, the configuration might share such objects or compute them according to some rules.

Clients should subclass and override just those methods which must be specific to their needs.
