is there a way to provide dependencies of the same type and inject them all together as a list? multibindings

I've injected lists of dependencies, used a named parameter

[Scott Kruse]

not sure about the multibinding though

[Marko Novakovic]

@Scott Kruse I need koin to recognise and group multiple objects of the same type into list and give me ability to use that list. I don’t want to create list myself

[Scott Kruse]

Why should Koin arbitrarily put objects of the same type into a list and assume you need it in this way? You need to tell Koin your dependencies. Koin just fetches what YOU tell it to via Qualifer

[Scott Kruse]

There is internal Koin logic that does what you're saying, but not sure why it would be exposed publicly

[Scott Kruse]

from InstanceRegistry.kt

@Suppress("UNCHECKED_CAST")
    internal fun <T> getAll(clazz: KClass<*>): List<T> {
        val instances = instances.values.toSet()
        val potentialKeys: List<InstanceFactory<*>> =
                instances.filter { instance -> instance.beanDefinition.hasType(clazz) }
        return potentialKeys.mapNotNull {
            it.get(defaultInstanceContext(null)) as? T
        }
    }

am just talking about multibindings. it’s well known feature in Dagger for example and it’s really useful

[Marko Novakovic]

I don’t want it arbitrarily putting objects in lists lol. just what I tell it to. and it could do that on it’s own, Dagger has annotation for that, and I don’t want to provide list which is error prone. you forget something….. BOOM on runtime

[Scott Kruse]

ah i see, sorry didn't fully understand what you meant in the original post

quick google search showed this: https://github.com/InsertKoinIO/koin/issues/772

single { FooBarJob(get()) } bind Job::class
getKoin().getAll<Job>()

good luck to you 👍

thank you very much!
