FSUnaryFileSystem
An abstract base class for implementing a minimal file system.
Declaration
class FSUnaryFileSystemOverview
FSUnaryFileSystem is a simplified file system, which works with one FSResource and presents it as one FSVolume.
The one volume and its container have a shared state and lifetime, a more constrained life cycle than the FSFileSystem design flow.
Implement your app extension by providing a subclass of FSUnaryFileSystem as a delegate object. Your delegate also needs to implement the FSUnaryFileSystemOperations protocol so that it can load resources.
