Method Detail

getUnsavedIdentifierValueback to summary
public static IdentifierValue getUnsavedIdentifierValue(String unsavedValue, Getter identifierGetter, Type identifierType, Constructor<T> constructor)

Return an IdentifierValue for the specified unsaved-value. If none is specified, guess the unsaved value by instantiating a test instance of the class and reading it's id property, or if that is not possible, using the java default value for the type

Parameters
unsavedValue:String

The mapping defined unsaved value

identifierGetter:Getter

The getter for the entity identifier attribute

identifierType:Type

The mapping type for the identifier

constructor:Constructor<T>

The constructor for the entity

Returns:IdentifierValue

The appropriate IdentifierValue

getUnsavedVersionValueback to summary
public static VersionValue getUnsavedVersionValue(String versionUnsavedValue, Getter versionGetter, VersionType<T> versionType, Constructor<T> constructor)

Return an IdentifierValue for the specified unsaved-value. If none is specified, guess the unsaved value by instantiating a test instance of the class and reading it's version property value, or if that is not possible, using the java default value for the type

Parameters
versionUnsavedValue:String

The mapping defined unsaved value

versionGetter:Getter

The version attribute getter

versionType:VersionType<T>

The mapping type for the version

constructor:Constructor<T>

The constructor for the entity

Returns:VersionValue

The appropriate VersionValue

instantiateback to summary
private static Object instantiate(Constructor<T> constructor)

Instantiate a class using the provided Constructor

Parameters
constructor:Constructor<T>

The constructor

Returns:Object

The instantiated object
