Constructor & Destructor Documentation

◆ Global() [1/5]

V8_INLINE Global ( )
inline

A Global with no storage cell.

Definition at line 377 of file v8-persistent-handle.h.

References Local< T >::PersistentBase.

◆ Global() [2/5]

V8_INLINE Global ( Isolate *  isolate,
Local< S >  that 
)
inline

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

References Local< T >::PersistentBase.

◆ Global() [3/5]

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

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

References Local< T >::PersistentBase.

◆ Global() [4/5]

Global ( Global< T > &&  other)

Move constructor.

Member Function Documentation

◆ operator=() [1/3]

void operator= ( const Global< T > &  )
