calculateDefaultPaths

public File[] calculateDefaultPaths(boolean for_moving)

Description copied from interface: Download

Returns an array of size 2 indicating the appropriate locations for this download's data files and torrent file, based on Azureus's rules regarding default save paths, and move on completion rules.

This method takes one argument - for_moving. This essentially indicates whether you are getting this information for purposes of just finding where Azureus would store these files by default, or whether you are considering moving the files from its current location.

If for_moving is false, this method will determine locations for the download and the torrent file where Azureus would store them by default (it may return the current paths used by this download).

If for_moving is true, then this method will consider the download's current location, and whether it is allowed to move it - you may not be allowed to move this download (based on Azureus's current rules) if the download doesn't exist within a default save directory already. If a download is complete, we consider whether we are allowed to move downloads on completion, and whether that includes downloads outside the default save directory.

In this case, the array may contain null indicating that the Azureus doesn't believe that the download should be moved (based on the current rules the user has set out). However, you are not prevented from changing the location of the torrent file or download.

Specified by:

calculateDefaultPaths in interface Download

Parameters:

for_moving - Indicates whether you want this information for the purposes of moving the download or not.

Returns:

An array of type File of size 2, first element containing the calculated location for the download's data files, and the second element containing the location for the download's torrent file.
