Nested classes

July 1, 2011

Too often I have seen something like

class Myclass

  class << self'

    def some_method

    end

  end

end

That is identical to

class myclass

  def self.some_method

  end

end

It can be seen that the use of class << self  end block can be to group together class methods. But there are more resons. example using alias_method_chain on class level methods

class Myclass

  class << self

    alias_method_chain :class_name, :feature

    attribute_accessor : count

  end

end
