Function Documentation

bool Archon::Raytracer::exceptionCatchInfo (  Utilities::Exception::Formatter  format, string &  result )  [inline]

Extract information from the last thrown exception. It re-throws the last thrown exception, and then attepts to catch any of the exception types known to this library. If this succeeds then the specified formatter is used to produce 'result' and true is returned. If the exception is unknown to this library then it just returns false. This method is intended to be incorporated into similar methods in other libraries that interact with this library or in applications that need to check various different libraries for exceptions known to them. Example: namespace MyApp { bool exceptionCatchInfo(Archon::Utilities::Exception::Formatter format, string &result) { try { throw; } catch(MyFooException &e) { result = (*format)(typeid(e), "", e.getMessage()) "; } catch(MyBarException &e) { result = (*format)(typeid(e), e.getLocation(), "") "; } catch(...) { return Archon::Utilities::exceptionCatchInfo(formatter, result) || SomeCoolLib::exceptionCatchInfo(formatter, result) || SomeShitLib::exceptionCatchInfo(formatter, result); } return true; } } int main(int argc, const char *argv[]) throw() { set_unexpected(Exception::terminal<MyApp::exceptionCatchInfo>); set_terminate(Exception::terminal<MyApp::exceptionCatchInfo>); ... } Note: If all your exceptions are derived from Archon::Utilities::Exception, then you do not need to write your own catchInfo function since Archon::Utilities::exceptionCatchInfo will know about it. If, on the other hand, you add new data to an exception derived from Utilities::Exception, and this data is not available through getMessage, you will need to provide your own exceptionCatchInfo to extract this data. See also: Exception::terminal Definition at line 36 of file exception.H. References Archon::Utilities::exceptionCatchInfo().
