Module | Sequel::Plugins::Subclasses
In: | lib/sequel/plugins/subclasses.rb

The Subclasses plugin keeps track of all subclasses of the current model class. Direct subclasses are available via the subclasses method, and all descendent classes are available via the descendents method.

      c = Class.new(Sequel::Model)
      c.plugin :subclasses
      sc1 = Class.new(c)
      sc2 = Class.new(c)
      ssc1 = Class.new(sc1)
      c.subclasses    # [sc1, sc2]
      sc1.subclasses  # [ssc1]
      sc2.subclasses  # []
      ssc1.subclasses # []
      c.descendents   # [sc1, ssc1, sc2]
