Class Overview

A strategy for determining if a version value is an version of a new transient instance or a previously persistent transient instance. The strategy is determined by the unsaved-value attribute in the mapping file.

Summary

Fields
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.
Public Constructors
VersionValue(Object value)
Assume the transient instance is newly instantiated if its version is null or equal to value
Protected Constructors

Public Methods
Object getDefaultValue(Object currentValue)
Boolean isUnsaved(Object version)
Does the given version belong to a new instance?
