示例1: AddXPConnectRoots

void XPCJSRuntime::AddXPConnectRoots(JSContext* cx,
                                     nsCycleCollectionTraversalCallback &cb)
{
    // For all JS objects that are held by native objects but aren't held
    // 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.

    JSContext *iter = nsnull, *acx;
    while((acx = JS_ContextIterator(GetJSRuntime(), &iter)))
    {
        // Only skip JSContexts with outstanding requests if the
        // callback does not want all traces (a debug feature).
        // Otherwise, we do want to know about all JSContexts to get
        // better graphs and explanations.
        if(!cb.WantAllTraces() &&
           nsXPConnect::GetXPConnect()->GetRequestDepth(acx) != 0)
            continue;
        cb.NoteRoot(nsIProgrammingLanguage::CPLUSPLUS, acx,
                    nsXPConnect::JSContextParticipant());
    }

    XPCWrappedNativeScope::SuspectAllWrappers(this, cx, cb);

    for(XPCRootSetElem *e = mVariantRoots; e ; e = e->GetNextRoot())
        cb.NoteXPCOMRoot(static_cast<XPCTraceableVariant*>(e));

    for(XPCRootSetElem *e = mWrappedJSRoots; e ; e = e->GetNextRoot())
    {
        nsIXPConnectWrappedJS *wrappedJS = static_cast<nsXPCWrappedJS*>(e);
        cb.NoteXPCOMRoot(wrappedJS);
    }

    if(mJSHolders.ops)
