org.eclipse.compare.internal.MergeViewerContentProvider

org.eclipse.compare.internal.MirroredMergeViewerContentProvider

All Implemented Interfaces:

IMergeViewerContentProvider, IContentProvider

public class MirroredMergeViewerContentProvider
extends MergeViewerContentProvider

This class just swaps the left and right input for display. The model values for left and right are not changed. We must extend from the class and not the interface, because some implementations expect the class.
