Parameters

Name	Type	Description
session	Session	The Session that will be used to load and save T persistent objects.
originalCollection	IEnumerable	An object that implements the IEnumerable interface.
copyFilter	CriteriaOperator	The CriteriaOperator that specifies the criteria for object selection from the originalCollection.
caseSensitive	Boolean	true if string comparisons are case-sensitive; otherwise, false. This value is assigned to the XPBaseCollection.CaseSensitive property.

Remarks

If the XPBaseCollection.LoadingEnabled property is set to true (default value) the collection is populated with T objects when its contents are accessed for the first time (for instance, when the XPBaseCollection.Count property is read).

The newly created collection will use the specified session to load and save persistent objects.
