Constructor & Destructor Documentation

Global() [1/5]

template<class T>

V8_INLINE Global ( )

default

A Global with no storage cell.

References V8_INLINE.

Referenced by Global(), Global(), operator=(), operator=(), and Pass().

Global() [2/5]

template<class T>

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

V8_INLINE 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.

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

V8_INLINE Global ( Isolate * isolate, const PersistentBase< S > & that )
