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.
