Module: ExtendObject

Defined in:
lib/buzztools/extend_object.rb

Overview

this pattern of declaring methods in a module and then including into a class means that the methods can be used directly from the module

eg. ExtendObject::attr_from_json(json,object)

or on the class it is included into

eg. model.attr_from_json(json)
