addAll method

void addAll (Iterable<E> iterable)
override

Appends all objects of iterable to the end of this list.

Extends the length of the list by the number of objects in iterable. Throws an UnsupportedError if this list is fixed-length.

Implementation

void addAll(Iterable<E> iterable) {
  int i = this.length;
  for (E element in iterable) {
    assert(this.length == i || (throw ConcurrentModificationError(this)));
    this.length = i + 1;
    this[i] = element;
    i++;
  }
}
