Field Summary

Modifier and Type	Field and Description
private static final Logger	log
public static final VersionValue	NEGATIVE Assume the transient instance is newly instantiated if the version is negative, otherwise assume it is a detached instance.
public static final VersionValue	NULL Assume the transient instance is newly instantiated if the version is null, otherwise assume it is a detached instance.
public static final VersionValue	UNDEFINED Assume the transient instance is newly instantiated if the version is null, otherwise defer to the identifier unsaved-value.
private final Object	value
