Field Summary

Modifier and Type	Field and Description
protected final transient LRUMap<ClassKey, QName>	_rootNames For efficient operation, let's try to minimize number of times we need to introspect root element name to use.
public static final QName	ROOT_NAME_FOR_NULL If all we get to serialize is a null, there's no way to figure out expected root name; so let's just default to literal `"null"`.
private static final long	serialVersionUID
