Interface IBiFunction<T,​U,​R>

  • 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
    All Superinterfaces:
    BiFunction<T,​U,​R>, Serializable
    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 IBiFunction<T,​U,​R>
extends BiFunction<T,​U,​R>, Serializable
    Represents a function that accepts two arguments and produces a result. This is the two-arity specialization of Function.

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

      default <V> IBiFunction<T,​U,​V> andThen​(Function<? super R,​? extends V> aAfter)

                                                   Function<? super R,​? extends V> aAfter)
        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.
        Specified by:
        andThen in interface BiFunction<T,​U,​R>
        Type Parameters:
        V - the type of output of the after function, and of the composed function
        Parameters:
        aAfter - 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
