Detailed Description

Base class for engine objects that may mutate, so their hash must be identity-based rather than content-based.

Note

AI-generated documentation. Verify against the source before relying on it.

Pulls a fresh integer from the static counter mNextMutableHashValue at construction and keeps it for the object's whole lifetime, so even after mutation hash() still returns the same value. Inherits from our_gc_cleanup so the GC can run a destructor when the object becomes unreachable (mutable objects often need to free non-GC resources).
