Implements "bag" semantics more efficiently than a regular PersistentBag by adding a synthetic identifier column to the table.

Namespace: NHibernate.Collection
Assembly: NHibernate (in NHibernate.dll) Version: 3.2.0.4000 (3.2.0.4000)

Syntax

C#
[SerializableAttribute]
public class PersistentIdentifierBag : AbstractPersistentCollection, 
	IList, ICollection, IEnumerable
Visual Basic
<SerializableAttribute> _
Public Class PersistentIdentifierBag _
	Inherits AbstractPersistentCollection _
	Implements IList, ICollection, IEnumerable
Visual C++
[SerializableAttribute]
public ref class PersistentIdentifierBag : public AbstractPersistentCollection, 
	IList, ICollection, IEnumerable

Remarks

The identifier is unique for all rows in the table, allowing very efficient updates and deletes. The value of the identifier is never exposed to the application.

PersistentIdentifierBags may not be used for a many-to-one association. Furthermore, there is no reason to use inverse="true".
