Marshal/Serialization Question

Bryan Richardson

8/19/2008 9:39:00 PM

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?

--
Thanks!
Bryan

Try it out. I'd say, most likely they are not dumped as classes are not
serialized IIRC. Class variables are evil anyway... :-)

Kind regards

That would seem to be a clear statement of separating religion and
government and his position.

So, what's the problem?

Biden's was written by by the staff of Sarurday Night Live.

Because the party platform doesn't conform to his personal beliefs.

Read his statement carefully.

The problem is that you are not clear on the separation of church and
state.

- When Nancy Reagan uses an Ouija board to consult with some god and
decide on US policy, the separation applies.

- If it is suggested that sacred wine must be drank before the
National Security Council meets, the separation applies.

- In the ObamaCare contraception, there is a border that should be
delineated.

THOSE are examples of issues where the separation doctrine applies.

However, when representatives from ALL churches make POLITICAL demands
and statements about immigration, those expressions of democracy are
VALID and deserve consideration.

NOBODY from your side has tried to discredit the religious leaders
below. It is in their job description to be on the side of compassion,
against hatred.
