// First checked in on 98/11/20 by John R. McMullen in the wrong directory.
// Checked in again 98/12/04.
// Polished version 98/12/08.
//========================================================================================
//
// Classes defined:
//
// nsFilePath, nsFileURL, nsFileSpec, nsPersistentFileDescriptor
// nsDirectoryIterator.
//
// Q. How should I represent files at run time?
// A. Use nsFileSpec. Using char* will lose information on some platforms.
//
// Q. Then what are nsFilePath and nsFileURL for?
// A. Only when you need a char* parameter for legacy code.
//
// Q. How should I represent files in a persistent way (eg, in a disk file)?
// A. Use nsPersistentFileDescriptor. Convert to and from nsFileSpec at run time.
//
// This suite provides the following services:
//
// 1. Encapsulates all platform-specific file details, so that files can be
// described correctly without any platform #ifdefs
//
// 2. Type safety. This will fix the problems that used to occur because people
// confused file paths. They used to use const char*, which could mean three
// or four different things. Bugs were introduced as people coded, right up
// to the moment Communicator 4.5 shipped.
//
// 3. Used in conjunction with nsFileStream.h (q.v.), this supports all the power
// and readability of the ansi stream syntax.
//
// Basic example:
//
// nsFilePath myPath("/Development/iotest.txt");
//
// nsOutputFileStream testStream(nsFileSpec(myPath));
// testStream << "Hello World" << nsEndl;
//
// 4. Handy methods for manipulating file specifiers safely, e.g. MakeUnique(),
// SetLeafName(), Exists().
//
// 5. Easy cross-conversion.
//
// Examples:
//
// Initialize a URL from a string
//
// nsFileURL fileURL("file:///Development/MPW/MPW%20Shell");
//
// Initialize a Unix-style path from a URL
//
// nsFilePath filePath(fileURL);
//
// Initialize a file spec from a URL
//
// nsFileSpec fileSpec(fileURL);
//
// Make the spec unique.
//
// fileSpec.MakeUnique();
//
// Assign the spec to a URL (causing conversion)
//
// fileURL = fileSpec;
//
// Assign a unix path using a string
//
// filePath = "/Development/MPW/SysErrs.err";
//
// Assign to a file spec using a unix path (causing conversion).
//
// fileSpec = filePath;
//
// Make this unique.
//
// fileSpec.MakeUnique();
//
// 6. Fixes a bug that have been there for a long time, and
// is inevitable if you use NSPR alone, where files are described as paths.
//
// The problem affects platforms (Macintosh) in which a path does not fully
// specify a file, because two volumes can have the same name. This
// is solved by holding a "private" native file spec inside the
// nsFilePath and nsFileURL classes, which is used when appropriate.
