    • isCompositionAllowed

      protected boolean isCompositionAllowed(org.eclipse.emf.ecore.EObject parent, org.eclipse.emf.ecore.EObject[] objects)
      Answers whether at least one of the given objects can be aggregated below the given parent as composite children.
      Parameters:
      parent - the composite parent
      objects - the objects to check
      Returns:

    • isResolvable

      protected boolean isResolvable(org.eclipse.emf.ecore.EObject object)
      Checks if the given EObject can be resolved in the local EditingDomain of the current DiagramBehavior. Pasting an EObject that is not resolvable (e.g. it was just created in another editor and has not yet been persisted) may cause issues with the graphical presentation of the new object: the Graphiti update will not find any domain object and will therefore mark the object as update needed (an update triggered will then remove the shape from the diagram). At least some special handling will be needed for the paste process of such an object: e.g. the domain object could be created along with its graphical presentation during IPasteFeature.paste(IPasteContext), but that may lead (depending on the domain) to other follow-up issues.
      Clients may use this method to check for such a situation and react accordingly. Created as part of the fix for Bugzilla 375533.
      Parameters:
      object - The object to check
      Returns:
      true in case the given object can be resolved in the editing domain of the current editor, false otherwise.
