Method Detail

extractDirectory

org.entityfs.Directory extractDirectory(ArchiveDirectoryEntry<?,?> dir,
                                      PotentialDirectory target,
                                      ExtractSpecification spec)

Extract a directory entry to the target directory.

Parameters:

dir - The directory entry.

target - The target directory.

spec - The extraction specification.

Returns:

The new directory or a previously existing directory if there already was a directory at the target location. If this operation did not result in there being a directory at the target location (if the target was occupied by a file that the overwrite strategy did not allow us to overwrite, for instance), this method returns null.
