Detailed Description

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

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

Constructor & Destructor Documentation

◆ ~TracedGlobal()

~TracedGlobal ( )
inline

Destructor resetting the handle.

Definition at line 940 of file v8.h.

◆ TracedGlobal() [1/6]

TracedGlobal ( )
inline

An empty TracedGlobal without storage cell.

Definition at line 945 of file v8.h.

References V8::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 V8::TracedReferenceBase.

◆ TracedGlobal() [3/6]

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

Move constructor initializing TracedGlobal from an existing one.

Definition at line 963 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 972 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 980 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 10929 of file v8.h.

◆ operator=() [2/6]

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

Copy assignment operator initializing TracedGlobal from an existing one.

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

◆ operator=() [4/6]

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

Move assignment operator initializing TracedGlobal from an existing one.

Definition at line 10919 of file v8.h.

◆ operator=() [5/6]

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

Move assignment operator initializing TracedGlobal from an existing one.

◆ operator=() [6/6]

Definition at line 10904 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 10894 of file v8.h.

References V8::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.
