QtDependencyResolver is a simple, ready-to-use library, that provide you ability to make IoC via DIContainer in your solution. DIContainer is based on Qt Meta-Object System and use invoke method to make a constructor injection.

You can bind your interfaces and base classes to a concrete implementation and retrieve instances later.

To bind your classes you must create a DIContainer instance and use the Bind method:

DIContainer* resolver = new DIContainer();
resolver->Bind<IUsersService, LocalUsersService>();
resolver->Bind<IUsersRepository, MongoDBUsersRepository>();

Then for resolving your interfaces or base classes you must use the Resolve method:

IUserService* userService = resolver->Resolve<IUsersService>();

Note: Only constructors that are declared with the Q_INVOKABLE modifier are made available to be invoked using QMetaObject::invokeMethod() through the meta-object system. For more details look on DIContainerTest.cpp in DependencyResolver-Tests library.
