#create_all_resources! ⇒ Object

PARSING MECHANISM

  • raise error if response not valid

  • look for included objects and parse them to resources

  • parse main object to resource

  • replace links in included resources with known resources

  • replace links in main resource with known resources

  • return main resource

    replace_links_with_known_resources @resource
  end

  @resource

  error
end

#create_resource(object) ⇒ Object

#detect_resource_class(object) ⇒ Object

Uses the resource mapping to find the proper Resource class to initialize for this Response object type

The mapping value can be a

  • Class

  • Proc: Will be called, expected to return the proper Class

  • Symbol: Will be called as method of the ResourceBuilder itself
