Is a Promise-returning, "oneshot" method useful?

[tobie]

This would be spec'ed along the lines of:

partial interface Sensor {
  Promise<SensorReading> oneshot(SensorInit sensorInitDic);
}

Useful when only a single reading is necessary (e.g. for certain geoloc usecases).

Rather easy to implement in JS on top of the existing primitives, but might enable some performance gains that would be unavailable otherwise.

I'd rather see how often this actually happens in practice, then iterate accordingly.

[tobie]

Agreed. Seems Geolocation requires it (cc @gmandyam, @timvolodine).

[tobie]

Seems from the use cases this is a requirement. Added it back to the spec. Closing.
