- class CHXFileSpecifier;
- class CHXDirSpecifier;
- // this utility class helps out the two classes below. It breaks a path up into these components:
- //
- // C:/dir1/dir2/dir3/file.ext
- // ^ ^ ^^ ^^
- //
- // Each arrow above points to the start of a component. The components are:
- //
- // volume
- // parent [path]
- // separator [note: this may be more than one character, for instance: c:/dir1////file1.txt, which is equivalent to c:/dir1/file1.txt]
- // name [for a file, the filename, for a directory, the directory name
- // extension separator [I think this is always a single '.']
- // extension [note that even directories may have extensions].
- //
- // Here are some special cases that are handled:
- //
- // /dir1/dir2/ -- a path with no volume, and trailing slash.
- //
- // volume: ""
- // parent: "/dir1"
- // separator: "/"
- // name: "dir2"
- // extension separator: ""
- // extension: ""
- //
- // \hostnamedrive_1devfile1.
- //
- // volume: "\hostname"
- // parent: "drive_1dev"
- // separator: ""
- // name: "file1"
- // extension separator: "."
- // extension: ""
- //
- // C:bogus.txt -- relative path, no directory
- //
- // volume: "C:"
- // parent: ""
- // separator: ""
- // name: "bogus"
- // extension separator: "."
- // extension: "txt"
