org.apache.airavata.gfac.bes.utils.FileTransferBase

org.apache.airavata.gfac.bes.utils.FileDownloader

public class FileDownloader
extends FileTransferBase

helper that exports remote files from a UNICORE Storage to the local client machine.
Simple wildcards ("*" and "?") and download of directories are supported. TODO this should be refactored so the single-file download logic is separated from the wildcard/directory/provided outputStream logic
