Module: ActsAsHashable::Factory

Extended by:
Forwardable
Defined in:
lib/acts_as_hashable/factory.rb

Overview

This class serves as a singleton that can make mapped acts_as_hashable components. It is important to note that these components must be acts_as_hashable objects. In order to use you just have to subclass this class and implement a method called ‘registry’, such as:

def registry
  {
    'Table': Table,
    'Text': Text
  }
end

You can also use the ‘register’ DSL:

register 'some_class_name', SomeClassName
register 'some_class_name', '', SomeClassName

or:

register 'some_class_name', ->(_key) { SomeClassName }
