Interface TriIntFunc<R>

  • 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 TriIntFunc<R>
    TriIntFunc Documentation.

    Primitive's Extension to Java's java.util.function.* package.

    This FunctionalInterface has an apply(...) method which accepts three primitives: three int-primitives.




    • Method Detail

      • apply

        R apply​(int i1,
                int i2,
                int i3)
        Applies a user-provided function to input aruments, returning a result of type R
        Parameters:
        i1 - The first integer-parameter.
        i2 - The second integer-parameter.
        i3 - The third integer-parameter.
        Returns:
        The result of the function. Return result is of type 'R'
      • andThen

        default <V> TriIntFunc<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'.
