Type Safety (TYPE)
Casts and type recognition.
Types, not Representations (NoRepr)
Rely on types, not on representations. Don't think in bits, don't memcpy non-PODs. -> Details
No switch on Types (NoSwitch)
Don't use switch, when the cases represent types. Prefer polymorphism. -> Details
No C-Style Casts (CCast)
Don't use C-Style casts, but the C++ casts. -> Details
Avoid static_cast on Pointers (StacaPtr)
Use dynamic_cast instead of static_cast when treating pointers polymorphically. -> Details
Related Rules
- No Implicit Conversions -> CLSDESIGN:NoConv
