Method Detail

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
