Interface ThrowingBiFunction<T,​U,​R,​X extends Exception>

  • Type Parameters:
    T - the type of the first argument to the function
    U - the type of the second argument to the function
    R - the type of the result of the function
    X - the type of the exception that might be thrown
    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 ThrowingBiFunction<T,​U,​R,​X extends Exception>
    Represents a function that accepts two arguments and produces a result. This is the two-arity specialization of Function.
    • Method Detail

      • apply

        R apply​(T t,
                U u)
         throws X extends Exception
        Applies this function to the given arguments.
        Parameters:
        t - the first function argument
        u - the second function argument
        Returns:
        the function result
        Throws:
        X - if the function invocation fails
        X extends Exception
      • andThen

        default <V> ThrowingBiFunction<T,​U,​V,​X> andThen​(ThrowingFunction<? super R,​? extends V,​? extends X> 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:
        V - 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
      • curryFirst

        default ThrowingFunction<U,​R,​X> curryFirst​(T t)
        Get a ThrowingFunction by currying the first parameter.
        Parameters:
        t - the constant parameter
        Returns:
        the function
      • currySecond

        default ThrowingFunction<T,​R,​X> currySecond​(U u)
        Get a ThrowingFunction by currying the second parameter.
        Parameters:
        u - the constant parameter
        Returns:
        the function
