SimpleEnvironmentBasedScope

class SimpleEnvironmentBasedScope(env: InjectionEnvironment) : InjectionScope

An injection scope that delegates the injection to the given environment, without any support for injecting from meta-environments.

Use the EnvironmentBasedScope constructor function to create the appropriate instance.

Constructors

fun SimpleEnvironmentBasedScope(env: InjectionEnvironment)

Functions

inject

open override 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).

Properties

Extensions

factory

inline fun <R : Any, T : Any> InjectionScope.~~factory~~(): ReadOnlyProperty<R, T>

DSL for injecting factory-made objects. Usage is factory from scope.

invoke

operator fun <T : Any> InjectionScope.invoke(identifier: Identifier<T>): ReadOnlyProperty<Any?, T>

Create an injector for the given identifier. See InjectionScope.inject for more information.

inline operator fun <T : Any> MetalessInjectionScope.invoke(qualifier: Qualifier = EmptyQualifier): ReadOnlyProperty<Any?, T>

Create an injector for the given class, turned to an identifier, and an optional qualifier. See InjectionScope.inject for more information.

optional

inline fun <T : Any> MetalessInjectionScope.optional(qualifier: Qualifier = EmptyQualifier): ReadOnlyProperty<Any?, T?>

Create an injector for the given class and optional qualifier. If such an identifier cannot be found within the environment, returns null (unlike other functions which throw a ComponentNotFoundException).
