DYNAMIC SYMBOLIC LINKS FOR COMPUTER FILE SYSTEMS

摘要

A user creates a rule defining file objects to appear at an arbitrary insertion point in a hierarchical file structure. Every request for a file, directory, etc. at the insertion point invokes the rule and constructs a set of dynamic links to actual locations of all file objects that satisfy the rule. Any operations performed by the program on the objects take place transparently on the objects at their actual locations. Between requests, the actual links go away, and only the rule for constructing them remains. An indexer operates continually to maintain current information on all files in the structure.
