Class: Qa::TermsController

Inherits:
ApplicationController show all
Defined in:

Overview

This controller is used for all requests to all authorities. It will verify params and figure out which class to instantiate based on the “vocab” param. All the authority classes inherit from a super class so they implement the same methods.
