示例1:

{
const dom::DOMClass* clasp = dom::GetDOMClass(obj);

}
示例2: AddXPConnectRoots

nsCycleCollectionTraversalCallback &cb)

// through rooting or locking, we need to add all the native objects that
// hold them so that the JS objects are colored correctly in the cycle
// collector. This includes JSContexts that don't have outstanding requests,
// because their global object wasn't marked by the JS GC. All other JS
// roots were marked by the JS GC and will be colored correctly in the cycle
// collector.
