class EventModerationPolicy

Library: IoT/Devices
Package: Devices
Header: IoT/Devices/EventModerationPolicy.h

Description

An EventModerationPolicy controls the frequency of events sent when an evented sensor or state variable changes. Any class or class template that fulfills the following criteria can be used as EventModerationPolicy:

  • The class must provide a public member function named valueChanged that takes as only argument the new value of the state variable (passed by const reference).
  • valueChanged() must check whether the criteria for firing an event are fulfilled, and in if this is the case, fire the event.
  • Typically, the Poco::BasicEvent instance will be passed to the policy object through the constructor.
