        Description copied from interface: MapIterable
        For each key and value of the map the function is evaluated. The results of these evaluations are returned in a new map. The map returned will use the values projected from the function rather than the original values.

        Description copied from interface: MapIterable
        Return the first key and value of the map for which the predicate evaluates to true when they are given as arguments. The predicate will only be evaluated until such pair is found or until all the keys and values of the map have been used as arguments. That is, there may be keys and values of the map that are never used as arguments to the predicate. The result is null if predicate does not evaluate to true for any key/value combination.
         Pair<City, Person> detected =
             peopleByCity.detect((City city, Person person) -> city.getName().equals("Anytown") && person.getLastName().equals("Smith"));
