Create new instances, optionally pass the first set

    # File lib/ramaze/snippets/ordered_set.rb, line 13
    def initialize(*args)
      if args.size == 1
        @set = args.shift
      else
        @set = *args
      end

      @set ||= []
      @set = [@set] unless ::Array === @set
      @set.uniq!
    end

### Public Instance Methods

[]=(*args) click to toggle source

    # File lib/ramaze/snippets/ordered_set.rb, line 34
    def []= *args
      @set.map! do |e|
        if ::Array === args.last
          args.last.include?(e) ? nil : e
        else
          args.last == e ? nil : e
        end
      end
      @set.__send__(:[]=, *args)
      @set.compact!
    end

method_missing(meth, *args, &block) click to toggle source

Delegate everything, but controlled, keep elements unique. Warning, this is not really atomic.

    # File lib/ramaze/snippets/ordered_set.rb, line 48
    def method_missing(meth, *args, &block)
      @set.__send__(meth, *args, &block)
    end
