Identity or Value?
Color, Money). Equality via comparison. Copyable.User, Socket). Equality via ID. Non-copyable (usually).| Issue | Design Question |
|---|---|
| Data Inconsistency | Are public fields allowing invalid states? |
| Object Slicing | Are you passing polymorphic Entities by Value? |
| Header Hell | Are you leaking implementation details? (Use Pimpl). |
Is it copyable?
Does it have invariants?
class with private data + public methods.struct (POD).Does it own others?
std::vector / unique_ptr.class User (Entity) holds Name (Value) and Address (Value).| Pattern | C++ Implementation |
|---|---|
| Value Object | struct + operator<=>. |
| Entity | class + Deleted Copy + ID field. |
| Repository | Pure Virtual Interface (virtual ... = 0). |
| Aggregate | Parent class owning children. |
