Function AutoSubscribe

AutoSubscribe<Ctor extends Constructor<object>>(
messageBus: MessageBus | (() => MessageBus),
onTransformedClass?: (transformedClass: Ctor, originalClass: Ctor) => void,
): ClassDecorator
Class decorator that automatically subscribes to topics based on method parameter decorators.

This decorator inspects the decorated class looking for methods with topic-decorated parameters, and subscribes to those topics using the provided messageBus.

When a message is published, the decorated parameter's method is invoked with the message data. If the class instance is garbage collected, the topic subscription is automatically disposed.
Type Parameters
- Ctor extends Constructor<object>
Parameters
- messageBus: MessageBus | (() => MessageBus)
  The message bus instance to use for creating subscriptions.
- OptionalonTransformedClass: (transformedClass: Ctor, originalClass: Ctor) => void
  An optional callback invoked with the class created by this decorator (transformedClass) and the original class (originalClass). Useful for registering the new class externally.
Returns ClassDecorator
Example
```
const messageBus = createMessageBus();

@AutoSubscribe(messageBus)
class UserManager {
  onUserLogin(@LoginTopic login: UserLogin): void {
    // ...
  }
}
```
