      • leastCommonAncestor

        public static org.eclipse.emf.ecore.EClass leastCommonAncestor​(Collection<org.eclipse.emf.ecore.EClass> classes)
        Get the wrapped least common ancestor of a collection of classes
        Parameters:
        classes - Collection of classes
        Returns:
        Wrapped least common ancestor

      • leastCommonAncestor

        public static org.eclipse.emf.ecore.EClass leastCommonAncestor​(org.eclipse.emf.ecore.EClass class1,
                                                               org.eclipse.emf.ecore.EClass class2)
        Get the wrapped least common ancestor of two classes
        Parameters:
        class1 - First class
        class2 - Second class
        Returns:
        Wrapped least common ancestor

      • ancestor

        public static boolean ancestor​(org.eclipse.emf.ecore.EClass class1,
                               org.eclipse.emf.ecore.EClass class2)
        Decide whether the second class is an ancestor of the first class
        Parameters:
        class1 - First class
        class2 - Second class
        Returns:
        true if the second class is an ancestor of the first class, false otherwise

      • commonSuperClass

        public static org.eclipse.emf.ecore.EClass commonSuperClass​(List<org.eclipse.emf.ecore.EObject> elements)
        Calculate the common super class of a list of instances
        Parameters:
        elements - List of instances
        Returns:
        Common super class

      • isCompatible

        public static boolean isCompatible​(org.eclipse.emf.ecore.EClassifier classifier,
                                   org.eclipse.emf.ecore.EClassifier withClassifier)
        Check whether a type can be used in the context where another type is expected
        Parameters:
        classifier - Actual type
        withClassifier - Expected type
        Returns:
        true if the actual type is compatible with the expected type, false otherwise
