Subject: Marshal/Serialization Question

Hello all,

I'm trying to Marshal some Ruby objects to file and I have a question
about parent classes.  Say I have the following:

class Device
  @@id         = 0
  @@id_map     = Hash.new
  @@device_map = Hash.new

  def initialize(*args)
    id               = @@id += 1
    @@id_map[self]   = id
    @@device_map[id] = self
  end

  def self.id(device)
    return @@id_map[device]
  end

  def self.device(id)
    return @@device_map[id]
  end
end

class Foo < Device
  def initialize
    super
  end
end

Now, if I create a Foo class, dump it to file and then load it again
using Marshal, should I be able to use the id and device methods in the
parent class or will the class variables not be dumped and loaded?
