What is Guice AssistedInject?

What is Guice AssistedInject?

AssistedInject allows you to dynamically configure Factory for class instead of coding it by yourself. This is often useful when you have an object that has a dependencies that should be injected and some parameters that must be specified during creation of object. Example from the documentation is a RealPayment.

What is assisted annotation?

Annotation Type Assisted Annotates an injected parameter or field whose value comes from an argument to a factory method.

What is assisted inject?

Assisted injection is a dependency injection (DI) pattern that is used to construct an object where some parameters may be provided by the DI framework and others must be passed in at creation time (a.k.a “assisted”) by the user.

What is dagger in Android?

Dagger is arguably the most used Dependency Injection, or DI, framework for Android. Many Android projects use Dagger to simplify building and providing dependencies across the app. It gives you the ability to create specific scopes, modules, and components, where each forms a piece of a puzzle: The dependency graph.

What is the difference between Dagger and hilt?

In Dagger-Android, we have to create a component class with a builder/factory, includes every module and we should inject the application context in the Application class after building our project. Hilt provides the ApplicationContextModule by default and it is followed by the whole application’s lifecycle.

What is @inject in Kotlin?

Inject is a new Kotlin multi-platform library that is a wrapper around the javax. inject annotations so that they can be used in Kotlin common code. Dagger is a popular dependency injection library, used on Android and the JVM, which processes the javax.

What is @inject in Android?

1 Answer. 1. For Android, these annotations are part of the Roboguice framework. They are used to provide dependency injection in an Android environment. This allows you to directly inject an instance of the desired resource, whether it’s a basic POJO, a view, or another resource.

What is the difference between Dagger and KOIN?

One notable piece of information worth mentioning is that while Dagger2 is a fully acknowledged DI project, whereas Koin is only described as a Service Locator. In Android programming, handling dependency is a big concern. For the past few years, we have been using Dagger2 for the dependency injection.

What is KTOR?

According to its official website, “Ktor is an open-source framework for building asynchronous servers and clients in connected systems using the powerful Kotlin programming language.” It runs on coroutines and was made by JetBrains. At present, it has JVM, iOS, JavaScript, and Android clients.

What is Kodein Kotlin?

Kodein (for KOtlin DEpendency INjection) is a DI framework. It allows you to bind your business unit interfaces with their implementation and thus having each business unit being independent. Kodein works exactly the same on all targets that are supported by Kotlin (JVM, Android, JS, Native).

What’s new in assistedinject in Guice 3?

AssistedInject in Guice 3.0. Guice 3.0 improves AssistedInject by offering the ability to allow different factory methods to return different types or different constructors from one type. See the FactoryModuleBuilder javadoc for complete details.

How do I visit an assistedinject binding in Guice?

Inspecting AssistedInject Bindings (new in Guice 3.0) Visiting an assisted inject binding is useful for tests or debugging. AssistedInject uses the extensions SPI to let you learn more about the factory binding. You can visit bindings with an AssistedInjectTargetVisitor to see details about the binding.

What is assistedassisted injection?

Assisted injection is a dependency injection (DI) pattern that is used to construct an object where some parameters may be provided by the DI framework and others must be passed in at creation time (a.k.a “assisted”) by the user. A factory is typically responsible for combining all of the parameters and creating the object.

Which assisted injection libraries should I use with dagger?

For Dagger users, we recommend using Dagger’s assisted injection rather than other assisted injection libraries like AutoFactory or square/AssistedInject. The existence of these libraries predate Dagger’s assisted injection. While they can be used with Dagger, they require a bit of extra boilerplate to integrate with Dagger.
