| JUMPDownloadDestination | | public interface JUMPDownloadDestination (Code) | | JUMPDownloadDestination provides the interface to
receive the data that is downloaded by the JUMPDownloadAction.
The start() is called first before the download operation
and if not exceptions are thrown by the method, then the
receive() method is called one or more times as the
downloading of data happens. Finally the finish() method
is called if the data has been successfully downloaded and delivered to
the destination or the abort() method is called if the
download operation was aborted by the user or the system.
