public Collection getNonNavigableInverseReferences(EObject eObject)

getInverseReferences

public Collection getInverseReferences(EObject eObject)

isIncluded

protected boolean isIncluded(EReference eReference)

createInverseCrossReferencer

protected ECrossReferenceAdapter.InverseCrossReferencer createInverseCrossReferencer()

notifyChanged

public void notifyChanged(Notification notification)

Handles a notification by calling selfAdapter.

Specified by:

notifyChanged in interface Adapter

Parameters:

notification - a description of the change.

selfAdapt

protected void selfAdapt(Notification notification)

Handles a notification by calling handleContainment for any containment-based notification.

handleContainment

protected void handleContainment(Notification notification)

Handles a containment change by adding and removing the adapter as appropriate.

handleCrossReference

protected void handleCrossReference(EReference reference,
                                    Notification notification)

Handles a cross reference change by adding and removing the adapter as appropriate.

setTarget
