addAll method Null safety
- 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.
Implementation
void addAll(Iterable<E> elements) {
for (E element in elements) {
int compare = _splay(element);
if (compare != 0) {
_addNewRoot(_SplayTreeSetNode(element), compare);
}
}
}
