Package play.inject

Interface Injector

  • All Known Implementing Classes:
    DelegateInjector
    public interface Injector
    An injector, capable of providing components.

    This is an abstraction over whatever dependency injection is being used in Play. A minimal implementation may only call newInstance on the passed in class.

    This abstraction is primarily provided for libraries that want to remain agnostic to the type of dependency injection being used. End users are encouraged to use the facilities provided by the dependency injection framework they are using directly, for example, if using Guice, use Injector instead of this.
