示例1: createWorkerContextProxy
// static
WorkerContextProxy* WebWorkerClientImpl::createWorkerContextProxy(Worker* worker)
{
// Special behavior for multiple workers per process.
// FIXME: v8 doesn't support more than one workers per process.
// if (!worker->scriptExecutionContext()->isDocument())
// return new WorkerMessagingProxy(worker);
WebWorker* webWorker = 0;
WebWorkerClientImpl* proxy = new WebWorkerClientImpl(worker);
