ComponentFactoryContainer

interface ComponentFactoryContainer (source)

Manages the factories to create the different components of Atrium. It takes basically the responsibility of a dependency injection facility, tailored for Atrium.

Functions

buildChainedOrNull	`abstract fun <I : Any> buildChainedOrNull(kClass: KClass<I>): Sequence<I>?` Returns a chain of components of type I using a corresponding chain of factories or `null` in case no chain was found which is able to build a chain of components of the given type.
buildOrNull	`abstract fun <I : Any> buildOrNull(kClass: KClass<I>): I?` Returns the component of type I using a corresponding factory or `null` in case no factory was found which is able to build a component of the given type.
getFactoryForChainedOrNull	`abstract fun getFactoryForChainedOrNull(kClass: KClass<*>): Sequence<ComponentFactory>?` Returns a chain of factories which shall build a chain of components of the specified kClass or `null` in case no chain was found which is able to build a chain of components of the given type.
getFactoryOrNull	`abstract fun getFactoryOrNull(kClass: KClass<*>): ComponentFactory?` Returns a factory which is able to build a component for the given kClass or `null` in case no factory was found which is able to build a component of the given type.
merge	`abstract fun merge(componentFactoryContainer: ComponentFactoryContainer?): ComponentFactoryContainer` Merges the given componentFactoryContainer (if not `null`) with `this` ComponentFactoryContainer creating a new ComponentFactoryContainer where defined dependencies in componentFactoryContainer will have precedence over dependencies defined in this instance.

Companion Object Functions

fun createIfNotEmpty(components: Map<KClass<*>, ComponentFactory>, chainedComponents: Map<KClass<*>, Sequence<ComponentFactory>>): ComponentFactoryContainer?

Extension Functions

build	`fun <I : Any> ComponentFactoryContainer.build(): I` Returns the component of type I using a corresponding factory or throws an IllegalStateException in case no factory was found which is able to build a component of the given type.
buildChained	`fun <I : Any> ComponentFactoryContainer.buildChained(): Sequence<I>` Returns a chain of components of type I using a corresponding factory or throws an IllegalStateException in case no factory was found which is able to build a chain of components of the given type.
