Package com.globalmentor.io.function

Interface IOToLongFunction<T>

Type Parameters:

T - the type of the input to the function

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 IOToLongFunction<T>

Represents a function that produces a long-valued result. This is the long-producing primitive specialization for IOFunction.

This interface is similar to ToLongBiFunction except that it is allowed to throw an IOException.
