Method Detail

of

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.

guicify

@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.

Since:

6.0

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.

Since:

3.0

guicify

public static <T> Provider<T> guicify(jakarta.inject.Provider<T> provider)

Returns a Guice-friendly com.google.inject.Provider for the given jakarta.inject.Provider. The converse method is unnecessary, since Guice providers directly implement the jakarta.inject.Provider interface.

Since:
