Interface QuadFunction<A,​B,​C,​D,​R>

  • Type Parameters:
    A - the type of the first argument to the function
    B - the type of the second argument to the function
    C - the type of the third argument to the function
    D - the type of the fourth argument to the function
    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 QuadFunction<A,​B,​C,​D,​R>
    Represents a function that accepts four arguments and produces a result. This is the four-arity specialization of Function.

    This is a functional interface whose functional method is apply(Object, Object, Object, Object).
