Constructor & Destructor Documentation

◆ Global() [1/5]

template<class T >
V8_INLINE Global ( )
default

A Global with no storage cell.

◆ Global() [2/5]

template<class T >
template<class S >
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.

Definition at line 379 of file v8-persistent-handle.h.

◆ Global() [3/5]

template<class T >
template<class S >
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.

Definition at line 391 of file v8-persistent-handle.h.

◆ Global() [4/5]

template<class T >
Global ( Global< T > &&  other)

Move constructor.

Member Function Documentation

◆ operator=() [1/3]

void operator= ( const Global< T > &  )
delete

◆ operator=() [2/3]

template<class T >
template<class S >
V8_INLINE Global & operator= ( Global< S > &&  rhs)

Move via assignment.

◆ operator=() [3/3]

template<class T >
template<class S >
Global< T > & operator= ( Global< S > &&  rhs)

Definition at line 560 of file v8-persistent-handle.h.

References v8::api_internal::MoveGlobalReference().

◆ Pass()

template<class T >
Global Pass ( )
inline

Pass allows returning uniques from functions, etc.
