Module: Servizio::Service::MethodDecorators

Included in:
Servizio::Service
Defined in:
lib/servizio/service.rb

Overview

This code does some metaprogramming magic. It overwrites .new, so that every instance of a class derived from Servizio::Service, gets a module prepended automatically. This way, one can easily “wrap” the methods, e.g. #call.

Defined Under Namespace

Modules: Call
