ContentMerge Viewers

Identifier:
org.eclipse.compare.contentMergeViewers

Description:
This extension point allows a plug-in to register compare/merge viewers for specific content types. 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.
