InjectionScope

interface InjectionScope : MetalessInjectionScope

An injection scope provides an entrypoint for components to retrieve the dependencies they need.

This should be passed as a constructor parameter to components that require injection. Use the InjectionScope.invoke operator to retrieve dependencies.

Functions

inject

abstract fun <T : Any> inject(what: Identifier<T>): Injector<T>

Create an injector for the given identifier. The behavior of the injection depends on the injection environment, but this is guaranteed to return an element of type T.

optional

open fun <T : Any> optional(what: Identifier<T>): Injector<T?>

Create an injector for the given identifier. If such an identifier cannot be found within the environment, returns null (unlike inject which throws a ComponentNotFoundException).
