Functions

template<typename T >
std::weak_ptr< T > to_weak (std::weak_ptr< T > w)
 Pointers that can be converted to a weak pointer concept for tracking purpose must implement the to_weak() function in order to make use of ADL to convert that type and make it usable. More...

Function Documentation

◆ to_weak() [1/2]

template<typename T >
std::weak_ptr< T > wpi::sig::trait::to_weak ( std::shared_ptr< T >  s)

◆ to_weak() [2/2]

template<typename T >
std::weak_ptr< T > wpi::sig::trait::to_weak ( std::weak_ptr< T >  w)

Pointers that can be converted to a weak pointer concept for tracking purpose must implement the to_weak() function in order to make use of ADL to convert that type and make it usable.
