  ऑब्जेक्ट संग्रहण टाईप गणना का विस्तार {type name = value val HTML}, text, SUBJECT = value} def read (key: स्ट्रिंग, _type: StorageType.Value = StorageType.HTML): स्ट्रिंग = {val प्रवेशकी = getPrefix (_type) + कुंजी DaoFactory.getPreviewStorageDao.get (accessKey) .data}

क्या इसका मतलब है मैं केवल StorageType.HTML को तर्क के रूप में भेज सकता हूं और नहीं StorageType.SUBJECT? इसके अलावा, मैं स्कैला के लिए बहुत नया हूँ ताकि आप मुझे बता सकें कि यहाँ क्या किया गया है?

कोड> _ टाइप पैरामीटर StorageType.Value उदाहरणों में से कोई एक हो सकता है, लेकिन यदि आप विधि को कॉल करते समय इसमें कोई भी उदाहरण नहीं डालते हैं, तो StorageType एचटीएमएल उदाहरण को स्वचालित रूप से असाइन किया जाएगा।
