Memoization

Memoization

If doing operations in a loop, the library provides a Memoize() action that will pull down the device list and cache it after running all filters. This will prevent recalculating the device list every iteration of the loop.

allLights := controller.Devices().
	TypeIs(veego.DeviceLight).
	Memoize()

err = allLights.On().Exec()
if err != nil {
	log.Fatal(err)
}

// Turn up the brightness from 0% to 100% in increments of 5%
for i := 0; i <= 100; i += 5 {
	err := allLights.
		Brightness(veego.Percentage(i)).
		Exec()
	if err != nil {
		log.Fatal(err)
	}

	fmt.Printf("Lamps at %d%%\n", i)
	time.Sleep(1 * time.Second)
}

Unlike other actions, additional filters could be applied to the query after memoizing it.
