示例1: trace
void trace(JSTracer* trc) override {
CrossCompartmentKey prior = key;
if (key.debugger)
TraceManuallyBarrieredEdge(trc, &key.debugger, "CCW debugger");
if (key.kind == CrossCompartmentKey::ObjectWrapper ||
key.kind == CrossCompartmentKey::DebuggerObject ||
key.kind == CrossCompartmentKey::DebuggerEnvironment ||
key.kind == CrossCompartmentKey::DebuggerSource)
{
MOZ_ASSERT(IsInsideNursery(key.wrapped) ||
key.wrapped->asTenured().getTraceKind() == JS::TraceKind::Object);
TraceManuallyBarrieredEdge(trc, reinterpret_cast<JSObject**>(&key.wrapped),
"CCW wrapped object");
}
if (key.debugger == prior.debugger && key.wrapped == prior.wrapped)
return;
/* Look for the original entry, which might have been removed. */
WrapperMap::Ptr p = map->lookup(prior);
if (!p)
return;
/* Rekey the entry. */
