Interface TriFunction<T,​U,​V,​R>

  • Type Parameters:
    T - the type of the first function argument
    U - the type of the second function argument
    V - the type of the third function argument
    R - the type of the function result
    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 TriFunction<T,​U,​V,​R>
    Represents a function that accepts three arguments and produces a result. This is the tri-arity specialization of Function. This is a functional interface whose functional method is apply(Object, Object, Object)
    • Method Detail

      • apply

        R apply​(T t,
                U u,
                V v)
        Applies this function to the given arguments.
        Parameters:
        t - the first function argument
        u - the second function argument
        v - the third function argument
        Returns:
        the function result
      • andThen

        default <W> TriFunction<T,​U,​V,​W> andThen​(Function<? super R,​? extends W> after)
        Returns a composed function that first applies this function to its input, and then applies the after function to the result. If evaluation of either function throws an exception, it is relayed to the caller of the composed function.
        Type Parameters:
        W - the type of output of the after function, and of the composed function
        Parameters:
        after - the function to apply after this function is applied
        Returns:
        a composed function that first applies this function and then applies the after function
        Throws:
        NullPointerException - if after is null
