Overview

Checks for a dbclient class instance variable with a cached client instance

This works on any module, class, or instance that implements has a dbclient method. From a Horreum model instance, if you call CachedConnectionHandler.new(self) it'll return self.dbclient or nil, or you can call CachedConnectionHandler(self.class) and it'll attempt the same using the model's class.

+familia_module+ is required.
