29 /** @brief Portable Path Abstraction
30 *
31 * Correct path and file names are dependent to the underlying OS and FS.
32 * Especially the set of forbidden characters (and their encodings / escape
33 * sequences) in path and file names differ on the various systems. This
34 * class is meant as a portable wrapper to circumvent these problems by
35 * storing the file names in its raw, human readable (intended) form and
36 * provides OS specific methods like @c toPosix() for converting the path into
37 * the correct encoding, as expected by the respective system.
38 *
39 * This class is currently only used internally by the LSCP parser. A lot
40 * generalization work would have to be done to use this class as a overall
41 * replacement for all @c char* / @c std::string file name arguments in the
42 * sampler or even its C++ API. Probably we'll use something like
43 * @c boost::filesystem::path instead of this class in future.
