TManagerEvents Class
Provides entity lifecycle and SQL execution events for an Aurelius mapping model.
Remarks
TManagerEvents is exposed through TMappingExplorer.Events. Subscribe handlers to its event properties before creating any TObjectManager backed by that explorer. All managers sharing the same explorer share the same event subscriptions.
Subscribing and unsubscribing handlers is not thread-safe; complete all registrations before the explorer is accessed concurrently from multiple threads.
