Detailed Description

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

A traced handle without destructor that clears the handle. The embedder needs to ensure that the handle is not accessed once the V8 object has been reclaimed. For more details see BasicTracedReference.

Definition at line 177 of file v8-traced-handle.h.

Constructor & Destructor Documentation

◆ TracedReference() [1/7]

template<typename T >

V8_INLINE TracedReference ( )

default

An empty TracedReference without storage cell.

◆ TracedReference() [2/7]

template<typename T >

template<class S >

TracedReference	(	Isolate *	isolate,
		Local< S >	that
	)

inline

Construct a TracedReference from a Local.

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

Definition at line 195 of file v8-traced-handle.h.

References IndirectHandleBase::IsEmpty(), v8::internal::kDefault, v8::internal::kInitializingStore, and V8_UNLIKELY.

◆ TracedReference() [3/7]

template<typename T >

template<class S >

TracedReference	(	Isolate *	isolate,
		Local< S >	that,
		IsDroppable
	)

inline

Construct a droppable TracedReference from a Local. Droppable means that V8 is free to reclaim the pointee if it is unmodified and otherwise unreachable

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