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. This can happen when the handle is not passed through the EmbedderHeapTracer. For more details see TracedReferenceBase.

The reference assumes the embedder has precise knowledge about references at all times. In case V8 needs to separately handle on-stack references, the embedder is required to set the stack start through |EmbedderHeapTracer::SetStackStart|.

Constructor & Destructor Documentation

◆ TracedReference() [1/6]

TracedReference ( )
inline

An empty TracedReference without storage cell.

References Local< T >::TracedReferenceBase.

◆ TracedReference() [2/6]

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.
