Can I do anything in this snippet to prevent the need from using a generic and passing in the

Class

as well?

abstract class BaseViewModelFragment<T : ViewModel>(private val type: Class<T>) : BaseInjectedFragment() {
    @Inject
    lateinit var viewModelFactory: ViewModelProvider.Factory
    private lateinit var viewModel: T

    override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
        super.onViewCreated(view, savedInstanceState)
        viewModel = ViewModelProviders.of(this, viewModelFactory).get(type)
    }
}

I don't know if it actually works: https://stackoverflow.com/questions/34122450/how-to-get-generic-parameter-class-in-kotlin Last comment

that must be reflection? haven't touched that before but im assuming so

I would not use like that, would explore and perhaps change to not need it.

how so @wbertan?

Good question...

holy

Check this:

bstract class BaseViewModelFragment<T : ViewModel> : Fragment() {
    lateinit var viewModelFactory: ViewModelProvider.Factory
    abstract val viewModel: T

    inline fun <reified K : ViewModel> asasMagic() = ViewModelProviders.of(this, viewModelFactory).get(K::class.java)

    override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
        super.onViewCreated(view, savedInstanceState)
    }
}

class OtherViewModelFragment: BaseViewModelFragment<ViewModel>() {
    override val viewModel: ViewModel
        get() = asasMagic()
}

so that definately makes sense using reified just not as abstracted away with having to get the viewmodel

are reified generics in inline methods methods a possibility? (first and only thought, I didn’t really look at the problem in depth)

wound up doing this

abstract class BaseViewModelFragment : BaseInjectedFragment() {
    @Inject
    lateinit var viewModelFactory: ViewModelProvider.Factory

    /**
     * Lazily get the view model
     */
    inline fun <reified VM : ViewModel> viewModel() = lazy {
        ViewModelProviders.of(this, viewModelFactory).get(VM::class.java)
    }
}
