object --+ | AbstractScanner --+ | FileScanner
Scans the filesystem for files that match the selection paths.
The scanner is configured with a root directory. Any number of include and exclude paths can be added. The scan() method is a generator that returns matching files one at a time when called as an iterator.
This is a revisited implementation of the filescanner. It now relies on the module pathaddition.match that implements a Ant-like regular expression matcher.
Rules: - Includes and excludes should not start with * - Includes and excludes should not have wildcard searches ending with ** (e.g. wildcard**)
Supported includes and excludes: - filename.txt - filename.* - dir/ - dir/* - dir/**

Finds all the subdirectory roots based on the include paths. Often large archive operations define a number of archives from the root of the drive. Walking the tree from the root is very time-consuming, so selecting more specific subdirectory roots improves performance. |
