Session.GetObjectsToSave() Method

Returns a collection of objects that will be saved when the current transaction is committed.

Namespace: DevExpress.Xpo

Assembly: DevExpress.Xpo.v24.2.dll

Declaration

C#

public ICollection GetObjectsToSave()

VB.NET

Public Function GetObjectsToSave As ICollection

Returns

Type	Description
ICollection	The collection of persistent objects that will be saved when the current transaction is committed.

Remarks

For general information on saving persistent objects, see Persisting Objects.

Objects that have Deferred Deletion enabled are actually modified upon deletion. So, they appear in the collection returned by the Session.GetObjectsToSave method, not in the collection returned by the Session.GetObjectsToDelete method.

The Session.GetObjectsToSave and Session.GetObjectsToDelete methods do not create new collection instances and fill them with objects when called. Instead, these methods return references to internal collections whose content changes throughout the life cycle of a Session.

C#

ICollection changedObjects = myUnitOfWork.GetObjectsToSave();
int count = changedObject.Count; // 'count' is an arbitrary number
myUnitOfWork.CommitChanges();
count = changedObject.Count; // here, 'count' always equals zero

VB.NET

Dim changedObjects As ICollection = myUnitOfWork.GetObjectsToSave()
Dim count As Integer = changedObject.Count ' 'count' is an arbitrary number
myUnitOfWork.CommitChanges()
count = changedObject.Count ' here, 'count' always equals zero
