Returns a new lazy
Iterable with all elements that satisfy the
The matching elements have the same order in the returned iterable
as they have in
This method returns a view of the mapped elements.
As long as the returned
Iterable is not iterated over,
the supplied function
test will not be invoked.
Iterating will not cache results, and thus iterating multiple times over
Iterable may invoke the supplied
test multiple times on the same element.
Iterable<E> where(bool test(E element)) => new WhereIterable<E>(this, test);
