All Implemented Interfaces: Set

Hash set implementation. Unordered collection of unique elements with average O(1) add/contains/remove. Internally backed by a HashMap<T, Boolean>. Example:

s = HashSet<String>()
s.add("red")
s.add("blue")
s.add("red")     # duplicate, size stays 2
assert "blue" in s
assert s.count("red") == 1
s.remove("red")

@param <T> Element type.
