Methods

Method	Description
IXRValueCollection::Add	Adds an item to the end of this collection and retrieves the index of where it was added.

IXRValueCollection::Contains	Determines whether an item is in this collection.

Thread Safety

Members of this class are thread-safe if you previously called IXRApplication::CreateHostFromXaml and supplied it with an XRWindowCreateParams structure that has AllowsMultipleThreadAccess set to true.

Remarks

This class is used internally to provide enumeration capabilities to collections of dependency properties and attached properties that are passed through methods in .

IXRValueCollection is an entry in the interface map for _XRValueCollectionBaseT<IFace,ItemType,ItemComparer,ItemConverter,ItemLifeManager>. Therefore, you can use IUnknown::QueryInterface to request an IXRValueCollection interface pointer to an instance of a collection object that inherits from _XRValueCollectionBaseT<IFace,ItemType,ItemComparer,ItemConverter,ItemLifeManager>.

If you create a class instance, use an IXRValueCollectionPtr smart pointer instead of a raw interface pointer. For more information about smart pointer aliases, see XRPtr<Interface>.
