34 * @class The SearchPath class is a helper class for getting a
35 * vector of paths contained in a search path string where a
36 * "search path string" contains absolute directory paths
37 * separated by a colon(:) or a semi-colon(;) on windows.
39 * The SearchPath class does not test whether the paths exist
40 * or are directories. It is basically just a container.
42 class SearchPath : public vector<sys::path>
46 * Create an empty SearchPath.
51 * Initialize SearchPath from a string where the string contains
52 * one or more absolute paths to directories which are delimited
53 * by a path separation character. The path delimeter is a
54 * colon(:) on unix and a semi-colon(;) on windows.
56 * Each path contained in the search path may or may not resolve to
57 * an existing directory in the filesystem.
59 * @param search_path A path string.
61 SearchPath (const string& search_path);
64 * Initialize SearchPath from a sys::path.
66 * @param directory_path A directory path.
68 SearchPath (const sys::path& directory_path);
71 * Initialize SearchPath from a vector of paths that may or may
76 SearchPath (const vector<sys::path>& paths);
79 * @return a search path string.
81 * The string that is returned contains the platform specific
84 const string to_string () const;
87 * Add all the directories in path to this.
89 SearchPath& operator+= (const SearchPath& spath);
92 * Add another directory path to the search path.
94 SearchPath& operator+= (const sys::path& directory_path);
97 * Concatenate another SearchPath onto this.
99 SearchPath& operator+ (const SearchPath& other);
102 * Add another path to the search path.
104 SearchPath& operator+ (const sys::path& directory_path);
107 * Add a sub-directory to each path in the search path.
108 * @param subdir The directory name, it should not contain
109 * any path separating tokens.
