I - the injectable type encountered

public interface TypeEncounter<I>
Context of an injectable type encounter. Enables reporting errors, registering injection listeners and binding method interceptors for injectable type I. It is an error to use an encounter after the hear() method has returned.

  • Method Details

    • addError

      void addError(String message, Object... arguments)
      Records an error message for type I which will be presented to the user at a later time. Unlike throwing an exception, this enable us to continue configuring the Injector and discover more errors. Uses String.format(String, Object[]) to insert the arguments into the message.
    • addError

      void addError(Throwable t)
      Records an exception for type I, the full details of which will be logged, and the message of which will be presented to the user at a later time. If your type listener calls something that you worry may fail, you should catch the exception and pass it to this method.
    • addError

      void addError(Message message)
      Records an error message to be presented to the user at a later time.
    • getProvider

      <T> Provider<T> getProvider(Key<T> key)
      Returns the provider used to obtain instances for the given injection key. The returned provider will not be valid until the injector has been created. The provider will throw an IllegalStateException if you try to use it beforehand.
    • getProvider

      <T> Provider<T> getProvider(Class<T> type)
      Returns the provider used to obtain instances for the given injection type. The returned provider will not be valid until the injetor has been created. The provider will throw an IllegalStateException if you try to use it beforehand.
    • getMembersInjector

      <T> MembersInjector<T> getMembersInjector(TypeLiteral<T> typeLiteral)
      Returns the members injector used to inject dependencies into methods and fields on instances of the given type T. The returned members injector will not be valid until the main injector has been created. The members injector will throw an IllegalStateException if you try to use it beforehand.
      Parameters:
      typeLiteral - type to get members injector for
    • getMembersInjector

      <T> MembersInjector<T> getMembersInjector(Class<T> type)
      Returns the members injector used to inject dependencies into methods and fields on instances of the given type T. The returned members injector will not be valid until the main injector has been created. The members injector will throw an IllegalStateException if you try to use it beforehand.
      Parameters:
      type - type to get members injector for
    • register

      void register(MembersInjector<? super I> membersInjector)
      Registers a members injector for type I. Guice will use the members injector after its performed its own injections on an instance of I.
    • register

      void register(InjectionListener<? super I> listener)
      Registers an injection listener for type I. Guice will notify the listener after all injections have been performed on an instance of I.
