/**
 * DON'T USE THIS INTERFACE AS IT'S SCHEDULED FOR REMOVAL IN THE UPCOMING MPS RELEASE
 *
 * This interface can be implemented to track write access of individual nodes in the model.
 * <p/>
 * Change listeners get notified regardless of model being attached to a repository. If, however, model
 * is attached to a repository, all notifications are delivered inside a write lock on the repository <b>after</b> a real change.
 * @deprecated use {@link org.jetbrains.mps.openapi.model.SNodeChangeListener} instead.
