Class Copier

java.lang.Object

EcoreUtil.Copier

org.gecko.emf.repository.helper.Copier

public class Copier
extends EcoreUtil.Copier

A mapping building traverser of a collection of content trees; the map is from EObject to EObject, i.e., from original to copy; use EcoreUtil.copy or EcoreUtil.copyAll to do routine copies. Since this implementation extends a Map implementation, it acts as the result of the over all copy. The client can call copy and copyAll repeatedly. When all the objects have been copied, the client should call copyReferences to copy the appropriate cross references.

  Copier copier = new Copier();
  EObject result = copier.copy(eObject);
  Collection results = copier.copyAll(eObjects);
  copier.copyReferences();

The copier delegates to copyContainment, copyAttribute during the copy phase and to copyReference, during the cross reference phase. This allows tailored handling through derivation.
