SplayTreeSet.from(Iterable elements, [ int compare(E key1, E key2), bool isValidKey(potentialKey) ])

Creates a SplayTreeSet that contains all elements.

The set works as if created by new SplayTreeSet<E>(compare, isValidKey).

All the elements should be valid as arguments to the compare function.


factory SplayTreeSet.from(Iterable elements,
    [int compare(E key1, E key2), bool isValidKey(potentialKey)]) {
  SplayTreeSet<E> result = new SplayTreeSet<E>(compare, isValidKey);
  for (final element in elements) {
    E e = element as Object/*=E*/;
  return result;
