Module: Workarea::Constants

Defined in:
lib/workarea/constants.rb

Overview

This module exists to help track constants for reflection at runtime. This is necessary because Rails’ autoloading will erase values stored in class or module accessors. This module must be loaded manually with ‘require`, for the same reason.
