All Implemented Interfaces:

org.eclipse.emf.common.notify.Adapter, org.eclipse.emf.common.notify.Adapter.Internal

public class AllInstancesContentAdapter
extends org.eclipse.emf.ecore.util.EContentAdapter

A content adapter that maintains a map of all EObjects in the scope observed (typically a ResourceSet), keyed by the EClasses to which the objects conform. This allows for fast lookup, e.g., of an allInstances() expression value in the given scope.

Method Detail

getInstanceForRootContextOf

public static AllInstancesContentAdapter getInstanceForRootContextOf(org.eclipse.emf.common.notify.Notifier context)

Looks up an adapter of type AllInstancesContentAdapter in the adapter list of context's root context. The root context is determined by ascending the EObject containment hierarchy, then to a Resource and perhaps a ResourceSet. The last element reachable in this order is the root context. If on this root context an adapter of type AllInstancesContentAdapter is already registered, it is returned. Otherwise, a new adapter of this class is created and added to the root context's adapter list. This will recursively apply the adapter to all contents, populating the adapter's allInstances map so that afterwards allInstances(EClass) returns results in the scope of context's root context.
