Initialization after YAML load?

ruby-talk
1

I'm saving and restoring a large tree structure using YAML. What I've
read is that the Initialize method is not called after loading.

Is there something like a post-load method within YAML that I can
override and is automatically invoked for each object created?

On a slightly related note, I've seen the to_yaml method but I'm looking
for the inverse. I want to save everything unless it's in my not_yaml
list. Does anything like this exist?

Thanks,
Larry Fast

you can use #to_yaml_properties() - return everything except the ones
you don't want to save. Works on a per attribute basis.

Thanks Jano,
That did the trick. As for the postload operations I'm taking a
different route.
