takeWhile method Null safety
- bool test(
- E value
override
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).
Implementation
Iterable<E> takeWhile(bool test(E value)) {
return TakeWhileIterable<E>(this, test);
}
