SortedSet

SortedSet implements a Set whose elements are sorted in ascending order (according to the return values of their <=> methods) when iterating over them.

Every element in SortedSet must be mutually comparable to every other: comparison with <=> must not return nil for any pair of elements. Otherwise ArgumentError will be raised.

Currently this library does nothing for JRuby, as it has its own version of Set and SortedSet.

Installation

Add this line to your application's Gemfile:

gem 'sorted_set'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install sorted_set

Usage

require "sorted_set"

set = SortedSet.new([2, 1, 5, 6, 4, 5, 3, 3, 3])
ary = []

set.each do |obj|
  ary << obj
end

p ary # => [1, 2, 3, 4, 5, 6]

set2 = SortedSet.new([1, 2, "3"])
set2.each { |obj| } # => raises ArgumentError: comparison of Fixnum with String failed
