• File src/OFNull.h — part of check-in [6ce0093f8d] at 2023-04-10 19:22:32 on branch trunk — Remove OFSerialization

  While the idea sounds nice that the tag name is the class, this means the
  serialization includes whether something is mutable or immutable. This means
  doing as much as making something immutable changes the serialization, which
  can then cause issues after being deserialized. (user: js, size: 1007) [annotate] [blame] [check-ins using] [more...]
