satcat5::poll::OnDemandHelper Class Reference

Detailed Description

Global helper object that services all OnDemand objects.

There is a single global instance of the OnDemandHelper class. It is the object that issues callbacks to all OnDemand objects that have requested attention.

This class inherits from Always, meaning that it is polled every time the user calls service or service_all, which causes it to check the global queue of OnDemand requests.
