29 * @class The SearchPath class is a helper class for getting a
30 * vector of paths contained in a search path string where a
31 * "search path string" contains absolute directory paths
32 * separated by a colon(:) or a semi-colon(;) on windows.
34 * The SearchPath class does not test whether the paths exist
35 * or are directories. It is basically just a container.
37 class SearchPath : public std::vector<std::string>
41 * Create an empty SearchPath.
46 * Initialize SearchPath from a string where the string contains
47 * one or more absolute paths to directories which are delimited
48 * by a path separation character. The path delimeter is a
49 * colon(:) on unix and a semi-colon(;) on windows.
51 * Each path contained in the search path may or may not resolve to
52 * an existing directory in the filesystem.
54 * @param search_path A path string.
56 SearchPath (const std::string& search_path);
59 * Initialize SearchPath from a vector of paths that may or may
62 * @param paths A vector of paths.
64 SearchPath (const std::vector<std::string>& paths);
67 * @return a search path string.
69 * The string that is returned contains the platform specific
72 const std::string to_string () const;
75 * Add all the directories in path to this.
77 SearchPath& operator+= (const SearchPath& spath);
80 * Add another directory path to the search path.
82 SearchPath& operator+= (const std::string& directory_path);
85 * Concatenate another SearchPath onto this.
87 SearchPath& operator+ (const SearchPath& other);
90 * Add another path to the search path.
92 SearchPath& operator+ (const std::string& directory_path);
95 * Add a sub-directory to each path in the search path.
96 * @param subdir The directory name, it should not contain
97 * any path separating tokens.
