org.eclipse.eef.ide.ui.properties.internal.RefreshIdsHolder

public final class RefreshIdsHolder
extends org.eclipse.emf.common.notify.impl.AdapterImpl

This class is responsible for providing an ID used during the refresh to match candidates and existing elements. We used to use EcoreUtil.getURI() but it was not performing well enough and could change when an attribute used as an eKeys was changed. The ID is associated with the element through the eAdapters mechanism and as such is stable as long as the element is there. This class is roughly based on RefreshIdsHolder in the Eclipse Sirius codebase.

Since:

2.0
