Class DiffMergeModelContextImpl

java.lang.Object
  org.eclipse.emf.ecp.view.internal.context.ViewModelContextImpl
      org.eclipse.emf.ecp.diffmerge.internal.context.DiffMergeModelContextImpl

All Implemented Interfaces:

DiffMergeModelContext, ViewModelContext

public class DiffMergeModelContextImpl
extends ViewModelContextImpl
implements DiffMergeModelContext

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