withSerializerUpgradesAllowed

@Nonnull
public abstract RegisteredStateMetaInfoBase withSerializerUpgradesAllowed()

create a new metadata object with Lazy serializer provider using existing one as a snapshot. Sometimes metadata was just created or updated, but its StateSerializerProvider will not allow further updates. So this method could replace it with a new one that contains a fresh LazilyRegisteredStateSerializerProvider.

fromMetaInfoSnapshot

public static RegisteredStateMetaInfoBase fromMetaInfoSnapshot(@Nonnull
                                                               StateMetaInfoSnapshot snapshot)
