| Module | Sequel::Plugins::Serialization::ClassMethods | 
| In: | lib/sequel/plugins/serialization.rb | 
| serialization_map | [R] | A map of the serialized columns for this model. Keys are column symbols, values are serialization formats (:marshal, :yaml, or :json). | 
| serialization_module | [RW] | Module to store the serialized column accessor methods, so they can call be overridden and call super to get the serialization behavior | 
Copy the serialization format and columns to serialize into the subclass.

          The first value in the serialization map. This is only for backwards compatibility, use serialization_map in new code.

          Create instance level reader that deserializes column values on request, and instance level writer that stores new deserialized value in deserialized columns
