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.
