Returns a lazy iterable of the leading elements satisfying test
.
The filtering happens lazily. Every new iterator of the returned iterable starts iterating over the elements of this
.
The elements can be computed by stepping through iterator until an element is found where test(element)
is false. At that point, the returned iterable stops (its moveNext()
returns false).
Iterable<E> takeWhile(bool test(E value)) { return new TakeWhileIterable<E>(this, test); }
