Detailed Description

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

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

The exact semantics are:

  • Tracing garbage collections using CppHeap.
  • 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, use |TracedReference| instead.
