Module: SuperCallbacks

lib/super_callbacks.rb,
lib/super_callbacks/helpers.rb,

lib/super_callbacks/class_and_instance_methods.rb

Overview

This is the module that will be prepended to the base (target) class where ‘include SuperCallbacks` have been called. This will be always a new instance of a Module, and will not be a permanent Module. This is important because, this module-instance is used by SuperCallbacks to define the methods whenever `before` or `after` is called. These defined methods here will then have a `super` inside it, which then will also call the “real” method defined in the target class.
