bsl::reference_wrapper< T > Class Template Reference

#include <bslmf_referencewrapper.h>

Detailed Description

template<class T>
class bsl::reference_wrapper< T >

This class is a copyable, rebindable proxy for a reference to an object or function. It encapsulates a reference into a value that can be reassigned to refer to a different target and can be stored where a native reference cannot, such as in a Standard Library container. A reference_wrapper is implicitly convertible to a reference to the represented type, so it can be passed to functions expecting such a reference.
