Various static methods that may help in CDO client applications.

registerResourceFactory

public static boolean registerResourceFactory(Resource.Factory.Registry registry)

getIntrinsicIDToEObjectMap

public Map<String,EObject> getIntrinsicIDToEObjectMap(CDOResource resource)

Returns the map used to cache the EObject that is identified by the value of its ID feature.

Returns:

the map used to cache the EObject that is identified by the value of its ID feature.

Since:

4.2

See Also:

setIntrinsicIDToEObjectMap(org.eclipse.emf.cdo.eresource.CDOResource, java.util.Map)

setIntrinsicIDToEObjectMap

public void setIntrinsicIDToEObjectMap(CDOResource resource,
                                       Map<String,EObject> intrinsicIDToEObjectMap)

Sets the map used to cache the EObject identified by the value of its ID feature. This cache is only activated if the map is not null. The map will be lazily loaded by the getEObjectByID method. It is up to the client to clear the cache when it becomes invalid, e.g., when the ID of a previously mapped EObject is changed.

Parameters:

intrinsicIDToEObjectMap - the new map or null.
