SignalRs

Server-side SignalR hub infrastructure: hub base class, session management, data source with change tracking, and client broadcast service.

Key Files

Hub

  • AcWebSignalRHubBase.cs — Abstract hub extending Hub<IAcSignalRHubItemServer>. Manages connection lifecycle, message dispatch via DynamicMethodRegistry, binary/JSON parameter deserialization. Response methods: ResponseToCaller(), SendMessageToOthers(), SendMessageToUserIdInternal().
  • IAcSignalRHubItemServer.cs — Server hub interfaces: IAcSignalRHubItemServer, IAcSignalRHubServer.
  • AcLoggerSignalRHub.cs — Specialized hub for receiving log items via SignalR (AddLogItem()).

Session & Broadcast

  • AcSessionService.cs — Generic session manager with ConcurrentDictionary<TSessionItemId, TSessionItem>.
  • IAcSessionItem.cs — Session item interface with SessionId property.
  • AcSignalRSendToClientService.cs — Abstract broadcast service: SendMessageToClient(), SendMessageToAllClients(), SendMessageToConnection(), SendMessageToUser().

Data Source

  • AcSignalRDataSource.cs — Server-side data source implementing IList<T> with change tracking (TrackingItem<T, TId>, ChangeTracking<T, TId>). Supports LoadDataSource(), LoadDataSourceFromResponseData() with binary/JSON deserialization.

Utilities

  • ExtensionMethods.cs — InvokeMethod() — invokes methods and unwraps Task/Task<T>/ValueTask results.
  • TrackingItemHelpers.cs — Deep clone helpers: JsonClone<T>(), ReflectionClone<T>().
