Definition: StringUtils.cpp:69
static std::string urlEncode(const std::string &url, const std::string encodeWhich="")
static bool toBool(const std::string &sData)
converts a string into the bool value described by it by calling the char-type converter ...
static std::string transcode(const XMLCh *const data)
