public interface IMerger

Mergers are used by EMF Compare to merge specific differences from one side to the other. A number of default mergers are provided by EMF Compare, but they can be sub-classed and extended by clients through the extension point "org.eclipse.emf.compare.ide.mergerExtension".

Clients are encouraged to subclass AbstractMerger instead of implementing IMerger so that they can benefit from a maximum of the common procedures.

Since:

3.0
