Hey all,

Is there an easy way of declaring a "list" of `single`s for a module? I wish to create a list of dependencies to be injected with getAll, and care not for the qualifier. Was hoping there was an easier way rather than defining a different qualifier each time as I have over 10 different classes in the list

I’ve just been playing around with this, and you should be able to make an extension function which generates a random qualifier for each binding. I’m not fully sure of the overall implications of it (in terms of scope pollution, etc.), but it does seem to work

inline fun <reified T> Module.addSingleToSet(
    createdAtStart: Boolean = false,
    override: Boolean = false,
    noinline definition: Definition<T>
): BeanDefinition<T> {
    val beanDefinition = DefinitionFactory.createSingle(
        named("${T::class.qualifiedName}_${randomAlphaNumericString()}"),
        definition = definition
    )
    declareDefinition(beanDefinition, Options(createdAtStart, override))
    return beanDefinition
}


inline fun <reified T> Module.addFactoryToSet(
    createdAtStart: Boolean = false,
    override: Boolean = false,
    noinline definition: Definition<T>
): BeanDefinition<T> {
    val beanDefinition = DefinitionFactory.createFactory(
        named("${T::class.qualifiedName}_${randomAlphaNumericString()}"),
        definition = definition
    )
    declareDefinition(beanDefinition, Options(createdAtStart, override))
    return beanDefinition
}

hmm, I was hoping that I didn't have to resort to something like that
