        public static <T> Provider<T> of​(T instance)
        Returns a provider which always provides instance. This should not be necessary to use in your application, but is helpful for several types of unit tests.
        Parameters:
        instance - the instance that should always be provided. This is also permitted to be null, to enable aggressive testing, although in real life a Guice-supplied Provider will never return null.

        @Deprecated
        public static <T> Provider<T> guicify​(Provider<T> provider)
        Deprecated.
        Marked as deprecated as a hint to users that calling this is unnecessary, because the provider is already a guice Provider.
        Returns itself. This exists primarily to avoid ambiguous method reference compile errors when calling guicify with a Guice provider.

      • guicify

        public static <T> Provider<T> guicify​(javax.inject.Provider<T> provider)
        Returns a Guice-friendly com.google.inject.Provider for the given JSR-330 javax.inject.Provider. The converse method is unnecessary, since Guice providers directly implement the JSR-330 interface.
