Returns the lazy concatentation of this iterable and other
.
The returned iterable will provide the same elements as this iterable, and, after that, the elements of other
, in the same order as in the original iterables.
Iterable<E> followedBy(Iterable<E> other) { // Type workaround because IterableMixin<E> doesn't promote // to EfficientLengthIterable<E>. Iterable<E> self = this; if (self is EfficientLengthIterable<E>) { return FollowedByIterable<E>.firstEfficient(self, other); } return FollowedByIterable<E>(this, other); }
