Properties

Readonly id

id: number

An id that represents a particular update check. Can be passed to nsIUpdateChecker::stopCheck.

Ids are guaranteed to be truthy (non-zero) and non-repeating. This is just for caller convenience so that (a) it's not an error to cancel a check that already completed and (b) they can easily check if (idVar) to see if they stored an id.

Readonly result

result: any

A promise that resolves to the results of the update check, which will be of type nsIUpdateCheckResult.
