An IList collection of persistent objects that are added, deleted or modified in the transaction currently in progress.
When you create, modify or delete an object, you should then call the BaseObjectSpace.CommitChanges method. This method saves all the changes made to the current Object Space's persistent objects to the database. To get the list of objects to be committed, use the ModifiedObjects property. After calling the BaseObjectSpace.CommitChanges method, this list is empty until creating, modifying or deleting an object.
