Class: ObservationPoll

browser.ObservationPoll Hosts the verified observe.poll program for one polling loop: report each observation or failure and wait the returned delay. The program slows polling once an observation stops changing and retries a temporary failure on the graph’s retry schedule, never sooner than the server’s Retry-After.
