  19. <p><!-- begin discussion --> The core set of file system operations the delegate must implement.
    20. 

  20. Unless otherwise noted, they typically should behave like the NSFileManager 
    21. 

  21. equivalent. However, the error codes that they return should correspond to
    22. 

  22. the BSD-equivalent call and be in the NSPOSIXErrorDomain.<br><br>
    23. 

  23. For a read-only filesystem, you can typically pick-and-choose which methods
    24. 

  24. to implement.  For example, a minimal read-only filesystem might implement:</p>
    25. 

  25. <ul>
    26. 

  26. - (NSArray *)contentsOfDirectoryAtPath:(NSString *)path 
    27. 

  27. error:(NSError **)error;<br>
    28. 

  28. - (NSDictionary *)attributesOfItemAtPath:(NSString *)path
    29. 

  29. userData:(id)userData
    30. 

  30. error:(NSError **)error;<br>
    31. 

  31. - (NSData *)contentsAtPath:(NSString *)path;</ul>
    32. 

  32. <p>
    33. 

  33. For a writeable filesystem, the Finder can be quite picky unless the majority
    34. 

  34. of these methods are implemented. However, you can safely skip hard-links, 
    35. 

  35. symbolic links, and extended attributes.
