followedBy method
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) sync* {
// TODO(lrn): Optimize this (some operations can be more efficient,
// and the concatenation has efficient length if the source iterables do).
yield* this;
yield* other;
}
