לא רצוי לחסום את RPC.
סיווג OperationFuture
הדרך הברורה ביותר לאינטראקציה עם מעבדי LRO היא
OperationFuture. אם משתמשים באפשרות הזו, צריך לוודא שלקוח השירות לא מושמד.
לא מומלץ:
privatevoiddoSomething(){OperationFuture<Empty,Empty>future=startLongRunningOperation(jobName);future.get();}privateOperationFuture<Empty,Empty>startLongRunningOperation(StringjobToStart)throwsUnsupportedEncodingException{try(OfflineUserDataJobServiceClientofflineUserDataJobServiceClient=googleAdsClient.getLatestVersion().createOfflineUserDataJobServiceClient()){// Issues an asynchronous request to run the offline user data job for executing// all added operations.returnofflineUserDataJobServiceClient.runOfflineUserDataJobAsync(jobToStart);}}
