Detailed Description

template<typename T>
class v8::TracedGlobal< T >

A traced handle with destructor that clears the handle. For more details see TracedReferenceBase.

Definition at line 954 of file v8.h.

Constructor & Destructor Documentation

◆ ~TracedGlobal()

~TracedGlobal ( )
inline

Destructor resetting the handle.

Definition at line 961 of file v8.h.

◆ TracedGlobal() [1/6]

TracedGlobal ( )
inline

An empty TracedGlobal without storage cell.

Definition at line 966 of file v8.h.

References Local< T >::TracedReferenceBase.

◆ TracedGlobal() [2/6]

TracedGlobal ( Isolate isolate,
Local< S >  that 
)
inline

Construct a TracedGlobal from a Local.

When the Local is non-empty, a new storage cell is created pointing to the same object.

References Local< T >::TracedReferenceBase.

◆ TracedGlobal() [3/6]

V8_INLINE TracedGlobal ( TracedGlobal< T > &&  other)
inline

Move constructor initializing TracedGlobal from an existing one.

Definition at line 984 of file v8.h.

◆ TracedGlobal() [4/6]

V8_INLINE TracedGlobal ( TracedGlobal< S > &&  other)
inline

Move constructor initializing TracedGlobal from an existing one.

Definition at line 993 of file v8.h.

◆ TracedGlobal() [5/6]

V8_INLINE TracedGlobal ( const TracedGlobal< T > &  other)
inline

Copy constructor initializing TracedGlobal from an existing one.

Definition at line 1001 of file v8.h.

◆ TracedGlobal() [6/6]

V8_INLINE TracedGlobal ( const TracedGlobal< S > &  other)
inline

Copy constructor initializing TracedGlobal from an existing one.

◆ operator=() [1/6]

TracedGlobal< T > & operator= ( const TracedGlobal< T > &  rhs)

Copy assignment operator initializing TracedGlobal from an existing one.

Note: Prohibited when |other| has a finalization callback set through |SetFinalizationCallback|.

Definition at line 11003 of file v8.h.

◆ operator=() [2/6]

V8_INLINE TracedGlobal& operator= ( const TracedGlobal< S > &  rhs)

Copy assignment operator initializing TracedGlobal from an existing one.

Definition at line 10978 of file v8.h.

◆ Reset() [1/2]

V8_INLINE void Reset ( Isolate isolate,
const Local< S > &  other 
)

If non-empty, destroy the underlying storage cell and create a new one with the contents of other if other is non empty

◆ Reset() [2/2]

void Reset ( Isolate isolate,
const Local< S > &  other 
)

Definition at line 10968 of file v8.h.

References Local< T >::TracedReferenceBase.

◆ SetFinalizationCallback()

void SetFinalizationCallback ( void *  parameter,
WeakCallbackInfo< void >::Callback  callback 
)

Adds a finalization callback to the handle. The type of this callback is similar to WeakCallbackType::kInternalFields, i.e., it will pass the parameter and the first two internal fields of the object.

The callback is then supposed to reset the handle in the callback. No further V8 API may be called in this callback. In case additional work involving V8 needs to be done, a second callback can be scheduled using WeakCallbackInfo<void>::SetSecondPassCallback.
