Returns a new lazy Iterable with elements that are created by calling f
on each element of this Iterable
in iteration order.
This method returns a view of the mapped elements. As long as the returned Iterable is not iterated over, the supplied function f
will not be invoked. The transformed elements will not be cached. Iterating multiple times over the returned Iterable will invoke the supplied function f
multiple times on the same element.
Methods on the returned iterable are allowed to omit calling f
on any element where the result isn't needed. For example, elementAt may call f
only once.
Iterable<T> map<T>(T f(E e)) => new MappedIterable<E, T>(this, f);
