Content Viewers

Identifier:
org.eclipse.compare.contentViewers

Description:
This extension point allows a plug-in to register viewers for specific content types. These viewers are used in the EditionSelectionDialog when presenting an edition of a resource or a subsection thereof. The viewer is expected to extend org.eclipse.jface.viewers.Viewer. However since viewers don't have a default constructor the extension point must implement the factory interface for viewers org.eclipse.compare.IViewerCreator.
