Controller and descendants

All controllers are singletons, retrieved via getInstance. They are handled mainly using the methods on[SomeEventName], called to register an event. All such methods have its own implementations. But generally their algorithm looks as follows:

  1. Create a required timeline record using [link=13963230]TimelineEntry[/link];
  2. If required, prepare data for showing the event at the frontend ([link=13963124]HistoryDataModel[/link]);
  3. Send push event.

FactoryBasedController - timeline controller for new entities.

CRM entities are gradually re-written for use of [link=13972404]new API[/link]. You need to prepare support for new approach to operation in various locations. Timeline is not an exception.

Due to this, abstract class was created \Bitrix\Crm\Timeline\FactoryBasedController. It's base for all timeline controllers for entities, operating, based on [link=13981986]factory[/link]. This class provides maximum universal implementation for event registering feature in timeline.
