See the documentation of the list() method in the parent class for the definition of how this method must behave. It implements the requirements specified there for a flat file system in the browser's localStorage object, as defined at the documentation for this class.

See the documentation of the read() method in the parent class for the definition of how this method must behave. It implements the requirements specified there for a flat file system in the browser's localStorage object, as defined at the documentation for this class.

Because this is a flat file system, any file object with a nonempty path member will not exist, regardless of its filename, and will therefore result in an error being thrown.

See the documentation of the write() method in the parent class for the definition of how this method must behave. It implements the requirements specified there for a flat file system in the browser's localStorage object, as defined at the documentation for this class.

Because this is a flat file system, any file object with a nonempty path member will not exist, regardless of its filename, and will therefore result in an error being thrown.
