// FilePath - a class for file and directory pathname manipulation which |
|
// handles platform-specific conventions (like the pathname separator). |
|
// Used for helper functions for naming files in a directory for xml output. |
|
// Except for Set methods, all methods are const or static, which provides an |
|
// "immutable value object" -- useful for peace of mind. |
|
// A FilePath with a value ending in a path separator ("like/this/") represents |
|
// a directory, otherwise it is assumed to represent a file. In either case, |
|
// it may or may not represent an actual file or directory in the file system. |
|
// Names are NOT checked for syntax correctness -- no checking for illegal |
|
// characters, malformed paths, etc. |
