Detailed Description

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

A traced handle with copy and move semantics. The handle is to be used together with |v8::EmbedderHeapTracer| or as part of GarbageCollected objects (see v8-cppgc.h) and specifies edges from C++ objects to JavaScript.

The exact semantics are:

• Tracing garbage collections use |v8::EmbedderHeapTracer| or cppgc.
• Non-tracing garbage collections refer to |v8::EmbedderRootsHandler::IsRoot()| whether the handle should be treated as root or not.

Note that the base class cannot be instantiated itself. Choose from

• TracedGlobal
• TracedReference
