Interface IntShortFunction<R>

  • Type Parameters:
    R - The type of the function-output.
    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 IntShortFunction<R>
    Function-Pointer Input: int, short Output: R.

    This is a function having an 'apply(...)' method which accepts two primitives-type parameters as follows type:

    1. 'int'
    2. 'short'


    The output of apply(...) follows the standard rules of Java's functional interfaces, and may be specified using the generic-type parameter 'R'.

        R apply​(int i,
        short s)
        Applies this function to the given arguments.
        Parameters:
        i - The integer (first) argument to the function.
        s - The short (second) argument to the function.
        Returns:
        The function result. Result shall be of type 'R'

        default <V> IntShortFunction<V> andThen​
            (java.util.function.Function<R,​V> 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 output-type of the 'after' function, and also of the (returned) 'composed' function.
        Parameters:
        after - The function to apply, after this function is applied.
        Throws:
        java.lang.NullPointerException - This throws if null is passed to 'after'.
        Code:
        Exact Method Body:
         if (after == null) throw new NullPointerException
     ("null has been passed to parameter 'after'");

 return (int i, short s) -> after.apply(this.apply(i, s));
