when

<F_> FunctionArbitrary<F_,R> when(java.util.function.Predicate<java.util.List> parameterCondition,
                                  java.util.function.Function<java.util.List,R> answer)

Type Parameters:

F_ - The exact functional type to generate. Must be same as F

Parameters:

parameterCondition - A predicate that's true when for the given list of parameters answer should be used to produce the function' result

answer - A function that produces a concrete answer or throws an exception

Returns:

A new instance of function arbitrary
