| /** |
| * <p> |
| * When used in tandem with {@link FactoryModuleBuilder}, constructors annotated with |
| * {@code @AssistedInject} indicate that multiple constructors can be injected, each with different |
| * parameters. AssistedInject annotations should not be mixed with {@literal @}{@link Inject} |
| * annotations. The assisted parameters must exactly match one corresponding factory method within |
| * the factory interface, but the parameters do not need to be in the same order. Constructors |
| * annotated with AssistedInject <b>are</b> created by Guice and receive all the benefits |
| * (such as AOP). |
| * |
| * <p> |
| * <strong>Obsolete Usage:</strong> When used in tandem with {@link FactoryProvider}, constructors |
| * annotated with {@code @AssistedInject} trigger a "backwards compatibility mode". The assisted |
| * parameters must exactly match one corresponding factory method within the factory interface and |
| * all must be in the same order as listed in the factory. In this backwards compatable mode, |
| * constructors annotated with AssistedInject <b>are not</b> created by Guice and thus receive |
| * none of the benefits. |
| * |
| * <p> |
| * Constructor parameters must be either supplied by the factory interface and marked with |
| * <code>@Assisted</code>, or they must be injectable. |
