Interface IntFunction<R>

  • Type Parameters:
    R - the type of the result of 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 IntFunction<R>
    Represents a function that accepts an int-valued argument and produces a result. This is the int-consuming primitive specialization for Function.

    This is a functional interface whose functional method is apply(int).
