| 3 | 1 | J. Wienke | h2. Error Handling / Exceptions |
| 4 | 1 | J. Wienke | |
| 5 | 1 | J. Wienke | * Use a common rsb::Exception for all exceptions |
| 6 | 1 | J. Wienke | ** In languages where multiple inheritance is a pain, this class inherits from a runtime-like error and a custom exception tree with e.g. InvalidArgument is created underneath this root exception type. |
| 7 | 1 | J. Wienke | ** If multiple inheritance is feasible, use it to reuse the existing language exception types. |
| 8 | 1 | J. Wienke | * in C++, don't use exceptions in constructors if you have objects that need a manual deallocation (to be verified that the destructor is not called for half-constructed instances) |
| 9 | 1 | J. Wienke | |
| 10 | 1 | J. Wienke | h3. Barricade Strategy |
| 11 | 1 | J. Wienke | |
| 12 | 1 | J. Wienke | * Generally user-induced data should be validated on the client level. |
| 13 | 1 | J. Wienke | * Exception to this rule is the converter mechanism -> user data member of the event class |
| 14 | 1 | J. Wienke | ** Generally performing a validation already in client-level code is too expensive |
| 15 | 1 | J. Wienke | ** OutRoute: |
| 16 | 1 | J. Wienke | *** Always using exceptions in the sending stack is not possible for asynchronous sending strategies. |
| 17 | 1 | J. Wienke | *** An invalid combination of data and converter is a (user-induced) fatal error |
| 18 | 1 | J. Wienke | *** exit the program (using a macro/function that creates a segfault in any case to get a backtrace, assert could be switched off and the error would be unnoticed or untraceable) |
