The default qualifier type.

If a bean does not explicitly declare a qualifier other than @Named, the bean has the qualifier @Default.

If an injection point declares no qualifier, the injection point has exactly one qualifier, the default qualifier @Default.

The following are equivalent:

@ConversationScoped
public class Order {

    private Product product;
    private User customer;

    @Inject
    public void init(@Selected Product product, User customer) {
        this.product = product;
        this.customer = customer;
    }

}

@Default
@ConversationScoped
public class Order {

    private Product product;
    private User customer;

    @Inject
    public void init(@Selected Product product, @Default User customer) {
        this.product = product;
        this.customer = customer;
    }

}
