restoreLazyManyToOneProperty

public static Object restoreLazyManyToOneProperty(GenericQueryManager manager,
                                                  Constrained constrained,
                                                  String propertyName,
                                                  String propertyTypeClassName)

Restores a constrained many-to-one property value that is lazily loaded.

Parameters:

manager - the GenericQueryManager that will be used to restore the related bean instance

constrained - the constrained bean instance that contains the property whose value will be restored

propertyName - the name of the property value that will be restored

propertyTypeClassName - the class name of the property that will be restored

Returns:

the value of the property, or

null if the constrained property doesn't exists or if it didn't have the manyToOne constraint
