Interface TriFunction<T,U,V,R>

Type Parameters:
T - the type of the first argument to the function
U - the type of the second argument to the function
V - the type of the third 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 TriFunction<T,U,V,R>
Represents a function that accepts three arguments and produces a result. This is the three-arity specialization of Function.

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

    • 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
    • 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
