Static methods:

• public static Set create ()
  Creates a new, initially empty set.
• public static Set get_empty ()
  Fetches the singleton empty Set.

Methods:

• public void @set (Set other)
  Makes the contents of set equal to the contents of other.
• public void add (Codepoint codepoint)
  Adds codepoint to set.
• public void add_range (Codepoint first, Codepoint last)
  Adds all of the elements from first to last (inclusive) to set.
• public Bool allocation_successful ()
  Tests whether memory allocation for a set was successful.
• public void clear ()
  Clears out the contents of a set.
• public void del (Codepoint codepoint)
  Removes codepoint from set.
• public void del_range (Codepoint first, Codepoint last)
  Removes all of the elements from first to last (inclusive) from set.
• public Codepoint get_max ()
  Finds the largest element in the set.
• public Codepoint get_min ()
  Finds the smallest element in the set.
• public uint get_population ()
  Returns the number of elements in the set.
• public Bool has (Codepoint codepoint)
  Tests whether codepoint belongs to set.
• public void intersect (Set other)
  Makes set the intersection of set and other.
• public void invert ()
  Inverts the contents of set.
• public Bool is_empty ()
  Tests whether a set is empty (contains no elements).
• public Bool is_equal (Set other)
  Tests whether set and other are equal ( contain the same elements).
• public Bool is_subset (Set larger_set)
  Tests whether set is a subset of larger_set.
• public Bool next (ref Codepoint codepoint)
  Fetches the next element in set that is greater than current value of codepoint.
• public Bool next_range (out Codepoint first, ref Codepoint last)
  Fetches the next consecutive range of elements in set that are greater than current value of last.
• public Bool previous (ref Codepoint codepoint)
  Fetches the previous element in set that is lower than current value of codepoint.
• public Bool previous_range (ref Codepoint first, out Codepoint last)
  Fetches the previous consecutive range of elements in set that are greater than current value of last.
• public void subtract (Set other)
  Subtracts the contents of other from set.
• public void symmetric_difference (Set other)
  Makes set the symmetric difference of set and other.
• public void union (Set other)
  Makes set the union of set and other .
