public protocol CSListObjectObserver : CSListObserver

Implement the CSListObjectObserver protocol to observe detailed changes to a list’s object. CSListObjectObservers may register themselves to a CSListMonitor‘s -addListObjectObserver(_:) method:

CSListMonitor *monitor = [CSCoreStore
    monitorListFrom:[CSFrom entityClass:[MyPersonEntity class]]
    fetchClauses:@[[CSOrderBy sortDescriptor:[CSSortKey withKeyPath:@"lastName" ascending:YES]]]];
[monitor addListObjectObserver:self];
