addAll method - SplayTreeSet class - dart:collection library (original) (raw)

description

void addAll(

1. Iterable<E> elements )

override

Adds all elements to this set.

Equivalent to adding each element in elements using add, but some collections may be able to optimize it.

final characters = <String>{'A', 'B'};
characters.addAll({'A', 'B', 'C'});
print(characters); // {A, B, C}

Implementation

void addAll(Iterable<E> elements) {
  for (E element in elements) {
    _add(element);
  }
}
