Platform::IBox Interface

The Platform::IBox interface is the C++ name for the Windows::Foundation::IReference interface.

Syntax

template <typename T>  
interface class IBox  

Parameters

T
The type of the boxed value.

Remarks

The IBox<T> interface is primarily used internally to represent nullable value types, as described in Value classes and structs (C++/CX). The interface is also used to box value types that are passed to C++ methods that take parameters of type Object^. You can explicitly declare an input parameter as IBox<SomeValueType>. For an example, see Boxing.
