This protected method implements collection operations that clear items in the collection.
Note
This method is reserved. In a derived class, call _XRValueCollectionBaseT.Clear instead of calling ClearItemsImpl.
Syntax
HRESULT STDMETHODCALLTYPE ClearItemsImpl(void)
Parameters
None.
Return Value
The following table shows the possible return values.
| Value | Description |
|---|---|
S_OK |
The method succeeded. |
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.
