All Implemented Interfaces:

DiffMergeModelContext, ViewModelContext, EMFFormsViewContext

public class DiffMergeModelContextImpl
extends ViewModelContextImpl
implements DiffMergeModelContext

Implementation of the DiffMergeModelContext based on the ViewModelContextImpl. As the ViewModelContextImpl is internal we suppress the restriction.
