# ContextStartedEvent constructor

ContextStartedEvent(

1. ApplicationContext source

)

Event published when the ApplicationContext is started or restarted.

This event indicates that the context is now active and ready to process requests, initialize pods, or resume tasks that may have been paused or stopped.

It is typically used after a call to `start()` or when a previously stopped context is reactivated.

### Example:

    class StartupLogger implements ApplicationListener<ContextStartedEvent> {
      @override
      void onApplicationEvent(ContextStartedEvent event) {
        print("Application context started: ${event.getSource()}");
      }
    }

## Implementation

    ContextStartedEvent(super.source);
