MoveOnlyTypeForCPP03

template<class T >

using v8::Global< T >::MoveOnlyTypeForCPP03 = void

Constructor & Destructor Documentation

Global() [1/5]

template<class T >

v8::Global< T >::Global ( )

inlinedefault

A Global with no storage cell.

Global() [2/5]

template<class T >

template<class S >
requires (std::is_base_of_v<T, S>)

v8::Global< T >::Global ( Isolate *  isolate, Local< S >  that  )

inline

Construct a Global from a Local with automatic up casting. When the Local is non-empty, a new storage cell is created pointing to the same object, and no flags are set.

Global() [3/5]

template<class T >

template<class S >
requires (std::is_base_of_v<T, S>)

v8::Global< T >::Global ( Isolate *  isolate, const PersistentBase< S > &  that  )

inline

Construct a Global from a PersistentBase with automatic up casting. When the Persistent is non-empty, a new storage cell is created pointing to the same object, and no flags are set.

Global() [4/5]

template<class T >

v8::Global< T >::Global ( Global< T > &&  other )

inline

Move constructor.

Here is the call graph for this function:

Pass()

template<class T >

Global v8::Global< T >::Pass ( )
