Interface Reader<R,A>

All Superinterfaces:

Bindable<Reader<R,?>,A>, Kind<Reader<R,?>,A>, Mappable<Reader<R,?>,A>, ReaderOf<R,A>

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public non-sealed interface Reader<R,A>
extends ReaderOf<R,A>, Bindable<Reader<R,?>,A>
