31 * @class The SearchPath class is a helper class for getting a
32 * vector of paths contained in a search path string where a
33 * "search path string" contains absolute directory paths
34 * separated by a colon(:) or a semi-colon(;) on windows.
36 * The SearchPath class does not test whether the paths exist
37 * or are directories. It is basically just a container.
39 class SearchPath : public std::vector<sys::path>
43 * Create an empty SearchPath.
48 * Initialize SearchPath from a string where the string contains
49 * one or more absolute paths to directories which are delimited
50 * by a path separation character. The path delimeter is a
51 * colon(:) on unix and a semi-colon(;) on windows.
53 * Each path contained in the search path may or may not resolve to
54 * an existing directory in the filesystem.
56 * @param search_path A path string.
58 SearchPath (const std::string& search_path);
61 * Initialize SearchPath from a sys::path.
63 * @param directory_path A directory path.
65 SearchPath (const PBD::sys::path& directory_path);
68 * Initialize SearchPath from a vector of paths that may or may
73 SearchPath (const std::vector<PBD::sys::path>& paths);
76 * @return a search path string.
78 * The string that is returned contains the platform specific
81 const std::string to_string () const;
84 * Add all the directories in path to this.
86 SearchPath& operator+= (const SearchPath& spath);
89 * Add another directory path to the search path.
91 SearchPath& operator+= (const PBD::sys::path& directory_path);
94 * Concatenate another SearchPath onto this.
96 SearchPath& operator+ (const SearchPath& other);
99 * Add another path to the search path.
101 SearchPath& operator+ (const PBD::sys::path& directory_path);
104 * Add a sub-directory to each path in the search path.
105 * @param subdir The directory name, it should not contain
106 * any path separating tokens.
