Method Detail

isGenericReference

public static boolean isGenericReference(org.eclipse.emf.ecore.EReference reference)

Check whether a reference is of generic type.

getNonGenericReference

public static org.eclipse.emf.ecore.EReference getNonGenericReference(org.eclipse.emf.ecore.EReference genericReference)

Get the corresponding reference which is not generic.

getGenericReference

public static org.eclipse.emf.ecore.EReference getGenericReference(org.eclipse.emf.ecore.EReference reference)

Get the corresponding reference which is generic.

copy
```
public static <V extends org.eclipse.emf.ecore.EModelElement> V copy(V modelElement)
```
Copy a metamodel element. Do not copy opposites in case this might lead to an inconsistency.

getAllRootPackages

public static Collection<org.eclipse.emf.ecore.EPackage> getAllRootPackages(org.eclipse.emf.ecore.resource.ResourceSet resourceSet)

Get all root packages in a resource set.

isMetamodelResource

public static boolean isMetamodelResource(org.eclipse.emf.ecore.resource.Resource resource)

Check whether the resource contains a metamodel.

isMetamodelURI

public static boolean isMetamodelURI(org.eclipse.emf.common.util.URI uri)

Check whether the URI denotes a resource containing a metamodel.

getRootPackage

public static org.eclipse.emf.ecore.EPackage getRootPackage(org.eclipse.emf.ecore.resource.ResourceSet resourceSet)

Get any root package in a resource set.

isConcrete
```
public static boolean isConcrete(org.eclipse.emf.ecore.EClass eClass)
```
Check whether a class is concrete, i.e. neither abstract nor an interface.

subtractTypes

public static List<org.eclipse.emf.ecore.EClass> subtractTypes(org.eclipse.emf.ecore.EClass minuend,
                                                               org.eclipse.emf.ecore.EClass subtrahend)

Subtract the types that are provided by a class from the types that are provided by another class.

subtractFeatures

public static List<org.eclipse.emf.ecore.EStructuralFeature> subtractFeatures(org.eclipse.emf.ecore.EClass minuend,
                                                                              org.eclipse.emf.ecore.EClass subtrahend)

Subtract the features that are provided by a class from the types that are provided by another class.

createIndependentMetamodelCopy

public static org.eclipse.emf.ecore.resource.ResourceSet createIndependentMetamodelCopy(Collection<org.eclipse.emf.ecore.EPackage> rootPackages,
                                                                                        org.eclipse.emf.common.util.URI metamodelURI)

Create a copy of a set of packages that is independent of generated packages.
