IWeakReference interface (weakreference.h)

  • Article

Represents a weak reference to an object.

Note

With only a few exceptions, weak reference support is on by default for Windows Runtime types that you consume or author in C++/WinRT, WRL, and C++/CX. Windows.UI.Composition and Windows.Devices.Input.PenDevice are examples of exceptions—that is, namespaces where weak reference support is not on for those types.

If you're authoring types, then see Weak references in C++/WinRT.

Inheritance

The IWeakReference interface inherits from the IUnknown interface.

Methods

The IWeakReference interface has these methods.

 
IWeakReference::Resolve

Resolves a weak reference by returning a strong reference to the object.
