A Download which can immediately be added to the download manager and afterwards executes some task, containing the logic of the download itself. A BackgroundTaskDownload gets his task via an implementation of the interface DownloadTask, see also strategy pattern. This means that different kind of tasks can be given to this download, which are then executed in the run()-Method. Such a task typically contains fetching the data needed for the download and then writing the download to a file. The File, which can be used, is provided by BackgroundTaskDownload.

Note 1: the download task will not run in the EDT.

Note 2: this download is not at all specialized and more specialized downloads for certain tasks may exists. E.g. JasperReportDownload
