Remarks
The _XRValueCollectionBaseT.Clear method invokes ClearItemsImpl, which calls _ItemLifeManager.ReleaseItem(Obj *) to release references to the objects in the _XRValueCollectionBaseT<IFace,ItemType,ItemComparer,ItemConverter,ItemLifeManager> collection, and then clears the item list.
You can override the ClearItemsImpl method implementation in a derived class. To do this, define a method called ClearItemsImpl in a class that inherits from _XRValueCollectionBaseT<IFace,ItemType,ItemComparer,ItemConverter,ItemLifeManager>, and write custom programming logic that releases the objects in the collection and clears the collection.
