followedBy method
- Iterable<
E> other
override
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.
Implementation
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);
}
