The DownloadQuery
type of the downloads
API defines a set of parameters that can be used to search the downloads manager for a specific set of downloads.
This type is used for example in downloads.search()
and downloads.erase()
, as a query object to filter the set of DownloadItems
to return or erase.
Values of this type are objects. They contain the following properties:
cookieStoreId
Optional

array
of string

for it to be included.startedBefore

that started before the given time.startedAfter
