std::vector< std::string > utils::quoted_split (const std::string &val, char c=',', int flags=REMOVE_EMPTY|STRIP_SPACES, char quote='\\')
 This function is identical to split(), except it does not split when it otherwise would if the previous character was identical to the parameter 'quote' (i.e. More...
