import type { EventManager } from './EventManager';
/**
 * Abstract base class for managers that subscribe to EventManager events
 *
 * Provides common initialization pattern for managers that need to listen to
 * player events through the EventManager. Eliminates duplicate code for
 * EventManager setup and event subscription across multiple managers.
 *
 * This is NOT a base for all managers - only for those that subscribe to events.
 * Managers like VideoManager, UIManager, CursorManager, etc. do not extend this.
 *
 * Usage:
 * ```typescript
 * export class MyManager extends EventSubscriberManager {
 *   protected subscribeToEvents(): void {
 *     if (!this.eventManager) return;
 *     this.eventManager.on('someEvent', this.handleEvent);
 *   }
 * }
 * ```
