static interface |
IFragmentProvider.Fallback
Delegate the resolution of EObject or the computation of fragments to the default implementation by invoking the respective methods on the given instance of this fall-back delegate. |

Method Detail |
---|
java.lang.String getFragment(org.eclipse.emf.ecore.EObject obj, IFragmentProvider.Fallback fallback)
obj
- the EObject to compute the fragment for.fallback
- if the default behavior should be used, delegate the
computation of the fragment to the default implementation of
Resource.getURIFragment(EObject)
.
null
.org.eclipse.emf.ecore.EObject getEObject(org.eclipse.emf.ecore.resource.Resource resource, java.lang.String fragment, IFragmentProvider.Fallback fallback)
resource
- the resource serves as context instance.fragment
- the fragment of the object.fallback
- if the fragment was not created by this provider, delegate the
resolution to the default implementation of
Resource.getEObject(String)
.
null
if the fragment could not be resolved to an object.
