System::Ref method

System::Ref(const std::reference_wrapper<T>&) method

Wrapper to make sure Ref(std::ref(DynamicWeakPtr)) works.

template<typename T> decltype(Ref(std::declval<T &>())) System::Ref(const std::reference_wrapper<T> &wrapper)

Parameter	Description
T	Referenced type.

Parameter	Type	Description
wrapper	const std::reference_wrapper<T>&	std wrapper to unwrap.

ReturnValue

Reference type defined in System:: rather than in std.

System::Ref(DynamicWeakPtr<T, trunkMode, weakLeafs…>&) method

Creates reference to DynamicWeakPtr object. Used by translator when passing function arguments by reference.

template<typename T,SmartPtrMode,unsigned int ...> DynamicWeakPtr<T, trunkMode, weakLeafs...>::Reference System::Ref(DynamicWeakPtr<T, trunkMode, weakLeafs...> &ptr)

Parameter	Description
T	Pointee type.
trunkMode	Mode of smart pointer itself.
weakLeafs	Indexes of template arguments for which SetTemplateWeakPtr method must be called.

Parameter	Type	Description
ptr	DynamicWeakPtr<T, trunkMode, weakLeafs…>&	Smart pointer to create reference to.

ReturnValue

Smart pointer reference.

System::Ref(T&) method

Helper function to acquire references to objects. Used to guarantee that System::DynamicWeakPtr updates referenced object after assignments.

Parameter	Description
T	Type to create reference to.

Parameter	Type	Description
value	T&	Value to create reference to.

ReturnValue

Reference to the value passed to this function.
