class fs.wrap.WrapCachedDir(wrap_fs)

Caches filesystem directory information.

This filesystem caches directory information retrieved from a scandir call. This may speed up code that calls isdir, isfile, or gettype too frequently.


Using this wrap will prevent changes to directory information being visible to the filesystem object. Consequently it is best used only in a fairly limited scope where you don’t expected anything on the filesystem to change.

class fs.wrap.WrapReadOnly(wrap_fs)

Makes a Filesystem read-only. Any call that would would write data or modify the filesystem in any way will raise a ResourceReadOnly exception.
