getEObject

public org.eclipse.emf.ecore.EObject getEObject(org.eclipse.emf.ecore.resource.Resource resource,
                                                java.lang.String fragment,
                                                IFragmentProvider.Fallback fallback)

Description copied from interface: IFragmentProvider

Locates an EObject in a resource by its fragment.

Specified by:

getEObject in interface IFragmentProvider

Parameters:

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).

Returns:

the resolved object or null if the fragment could not be resolved to an object.

getFragment

public java.lang.String getFragment(org.eclipse.emf.ecore.EObject obj,
                                    IFragmentProvider.Fallback fallback)

Description copied from interface: IFragmentProvider

Computes the URI fragment (local ID) of the given object.

Specified by:

getFragment in interface IFragmentProvider

Parameters:

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).

Returns:

the fragment, which can be an arbitrary string but must be unique within a resource. May not return null.
