Overview

Dumps a constant by using its name. On reload, #proxy searches for a constant with the same name, and raises ArgumentError if none exists.

Examples:

dump instances of a class that are registered as constants

class Klass
  include DRobyConstant::Dump
end
# Obj can pass through droby
Obj = Klass.new

dump classes. You usually would prefer using DRobyModel

# Klass can pass through droby
class Klass
  extend DRobyConstant::Dump
end
