ABSTRACT:
An object-oriented file system in an object-oriented operating system includes a file system entity class that is subclassed into a volume, directory and file subclass. These classes encapsulate standard file system properties such as name, creation date, and size, as well as standard operations such as create, open, close, and property accessors. Using object-oriented programming, the class properties and operations can easily be modified and extended. Also provided is a convenient and efficient means for searching through the entities, and collecting heterogeneous sets. Further, a category of notification classes is provided for notifying clients when an entity has changed. Still further, user authentication and protection domains are used to protect against unauthorized access. Finally, a means for working with foreign file systems running under different operating systems is provided.
