Detailed Description

Base class for engine objects that are immutable once their hash has been pinned (typically once they cross over to the front end).

Note

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

Holds a single lazily computed mHashValue that defaults to zero and is filled in by computeHashValue() (pure virtual — every subclass supplies its own hashing rule). The non-zero invariant doubles as a "computed yet" flag: hash() returns the cached value, or runs the computation and bumps a zero result to 1 so the flag still distinguishes uncomputed from "genuinely hashed to 0".
