|
|
A chained filesystem is designed to be layered over another FS.
|
|
This is useful to implement things like caching.
|
|
|
|
This base class does very little on its own, but is used as a marker
|
|
that the class is designed for chaining.
|
|
|
|
Right now this is only used in `url_to_fs` to provide the path argument
|
|
(`fo`) to the chained filesystem from the underlying filesystem.
|
|
|
|
Additional functionality may be added in the future.
