Package fj.data

Interface IO<A>

Type Parameters:

A - the type of the result produced by the IO

All Superinterfaces:

Try0<A,java.io.IOException>

All Known Subinterfaces:

SafeIO<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 interface IO<A>
extends Try0<A,java.io.IOException>

IO monad for processing files
