supportsDeserialization

Return true when this serializer should restore the serialized blackboard value.

Implementations usually inspect SerializedBlackboardValue.typeName, SerializedBlackboardValue.contentType, or metadata written during serialization.

The default returns false. A serializer that overrides only supportsSerialization and serialize will write values but never restore them — the fallback serializer handles deserialization instead, which will likely produce wrong results or fail. Override both supportsDeserialization and deserialize for a complete serialization round-trip.
