# isClosed method

1. @override

bool isClosed()
override

Returns whether this application context has been closed.

A closed context has completed its lifecycle and released all resources. Attempting to use a closed context will typically result in exceptions.

### Closed Context Behavior:

- Pod Access: `IllegalStateException` when retrieving pods
- Event Publishing: Events may be ignored or cause exceptions
- Configuration Access: Environment and configuration may be unavailable
- Resource State: Database connections, thread pools, etc. are closed

### Lifecycle:

    final context = MyApplicationContext();
    print(context.isClosed()); // false

    await context.refresh();
    print(context.isClosed()); // false

    await context.close();
    print(context.isClosed()); // true

## Implementation

    @override
    bool isClosed() => _isClosed;
