inline

Destructor resetting the handle.Is

Definition at line 983 of file v8.h.

◆ TracedGlobal() [1/6]

TracedGlobal ( )
inline

An empty TracedGlobal without storage cell.

◆ 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.

◆ Reset() [1/2]

V8_INLINE void Reset ( Isolate isolate,

◆ 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.
