static std::string current(); 　　Returns the current working directory.

int depth() const;　　　　　　　Returns the number of directories in the directory list.

const std::string & directory(int n) const; Returns the n'th directory in the directory list. If n == depth(), returns the filename.

bool isDirectory() const;Returns true if and only if the path references a directory (the filename part is empty).

　　　　　　只有路径字符串末尾是/的时候，判断为真，其余都是假。

bool isFile() const; Returns true if and only if the path references a file (the filename part is not empty).

　　　　　　路径字符串末尾不是/的时候，为真。

Path & makeDirectory();

　　　　If the path contains a filename, the filename is appended to the directory list and cleared. Thus the resulting path 　　　　　　always refers to a directory.

Path & makeFile();

　　If the path contains no filename, the last directory becomes the filename.

Path & makeParent();

　　Makes the path refer to its parent.

Path parent() const;

Returns a path referring to the path's directory.

std::string toString() const;

　　Returns a string containing the path in native format.
