Hi Ryan, “A periodic window like this requires the ability to start a timer without an element and to restart a timer when fired.”
For the second part, i.e. “to restart a timer when fired”, you can re-register the timer in the onTimer() method (set a new timer for “now + T"), so that the next one fires after T time units, where T is your period. For the first part, where you set the initial timer for a window, this needs to have a first element right? If not, how do you know the key for which to set the timer? Are all the keys known in advance?
