void addHistory(const std::string &msg_r)
Add some message text to the history.
History::const_iterator HistoryIterator
History::size_type HistorySize
static void log(const Exception &excpt_r, const CodeLocation &where_r, const char *const prefix_r)
Drop a logline on throw, catch or rethrow.
HistoryIterator historyBegin() const
Iterator pointing to the most recent message.
const char * what() const override
Return message string.
const std::string & msg() const
Return the message string provided to the ctor.
void remember(std::string &&msg_r)
exception_detail::CodeLocation CodeLocation
void moveToHistory(TContainer &&msgc_r)
addHistory from string container types (oldest first) moving
HistoryIterator historyEnd() const
Iterator pointing behind the last message.
void addToHistory(const TContainer &msgc_r)
addHistory from string container types (oldest first)
std::list< std::string > History
void relocate(const CodeLocation &where_r) const
Exchange location on rethrow.
HistorySize historySize() const
The size of the history list.
const CodeLocation & where() const
Return CodeLocation.
void remember(const std::string &msg_r)
Remembering a plain string is most probably not wanted - we addHistory.
