Whats the interface in angle brackets in Kotlin?

In Kotlin I often read

class MyFragment : BaseMvpFragment<MvpView, MvpPresenter>(), MvpView {}

whereas MvpView and MvpPresenter are interfaces.. so MyFragment extends BaseMvpFragment<MvpView, MvpPresenter>() but how can I interpret <MvpView, MvpPresenter> ?

They are type parameters; see here.

The class BaseMvpFragment obviously defines two generic types which are being specified via <MvpView, MvpPresenter>.

Consider the List<T> interface. When you implement it, it looks like this:

class VerySpecialList : List<String> { ... }
