IntFunction1 (core 3.0.0 API)

Type Parameters:

R - the type of the result of the function

All Superinterfaces:

Arity, FunctionN<R>, InputChainable<java.lang.Integer>, InputChainableInput<java.lang.Integer>, ResultChainable<R>, ResultChainableResult<R>, UnboxedInput<Function1<java.lang.Integer,R>>, Variant<java.util.function.IntFunction<R>>

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 IntFunction1<R>
extends FunctionN<R>, InputChainableInput<java.lang.Integer>, UnboxedInput<Function1<java.lang.Integer,R>>, Variant<java.util.function.IntFunction<R>>
```
Represents a function that accepts an int-valued argument and produces a result. This is the one-arity specialization of FunctionN. This is the int-consuming primitive specialization of Function1.
This is a functional interface whose functional method is apply(int).

Since:

3.0.0
