OcaSubscriptionManager

This document describes the device side implementation of OcaSubscriptionManager. This class is documented in the AES70 standard as:

Manager that collects and controls the event subscriptions of the device. Must be instantiated exactly once in every device., Object number must be 4.

---

Overview

• ClassID: 1.3.4
• Header: aes70/device/OcaSubscriptionManager.hpp
• Namespace: aes70::device
• Inheritance: aes70::device::OcaManager, aes70::device::OcaRoot, aes70::device::object

Class Declaration

The device side implementation has the following signature.

namespace aes70::device
{
  template <class Implementation>
  class OcaSubscriptionManager : public OcaManager<Implementation>
  {

  };
}

The template argument Implementation may implement the following methods.

Note

The signatures given here are just one possibility and that most methods are optional. Implement only those methods which make sense in the context of your device. See the documentation in Implementing AES70 Classes for more details.
