In Java 8, can the method reference part of a call always be parenthesized? -

-

मेरे पास एक सही जावा विधि कॉल है, जैसे कि 

  fg (5)

जावा 8 अब विधि संदर्भ की अनुमति देता है, इसलिए ज्यादातर मामलों में एक 

  (f :: g) (5)   
  प्रश्न : क्या यह हमेशा भी संभव है ऐसे मामलों में जहां  f :: g  अतिभारित है, या दो चरण प्रक्रिया से हस्तक्षेप कर सकते हैं? 
 
 प्रेरणा: मैं कंपाइलर-जैसी कोड लिख रहा हूं, यही वजह है कि मुझे इन सूटलेट्स को समझने की ज़रूरत है, यह ऐसा होगा यदि अधिभार निर्धारण विधि विधि के स्तर पर होना चाहिए। । मुझे पता है कि कॉल में विधि संदर्भ को कोष्ठक करने के लिए एक आवश्यक सॉफ़्टवेयर इंजीनियरिंग अभ्यास नहीं है।

नहीं।

हालांकि, मुझे लगता है कि आप इस सुविधा के बारे में भ्रमित हैं। उपरोक्त में f.g की कथन विधि संदर्भ नहीं है; यह एक अभिव्यक्ति भी नहीं है

एक विधि संदर्भ एक अभिव्यक्ति है जो Foo :: bar जैसा दिखता है और इसे एक कार्यात्मक इंटरफ़ेस प्रकार में कनवर्ट किया जा सकता है।

I am trying to use the ASP.NET signal for the first time - here's what I did: created a new web Has been added to the project and the following signal R packages: I have created the following category: [Hub-name ("chat")] Public class ChatHub: Hub {Public Zero Halo () {Clients.All.hello ( ); }} and the following startup configuration: public partial class startup {public zero configuration (IAppBuilder app) {configure (app); App.MapSignalR (); }} However, whenever I navigate localhost: (port) / api / signalr / chat I get the following error: Protocol error: Unknown transport. I am running a new browser and trying different people so remove it from the API / URL, and just use the localhost: (potter) / signaller / Chat

Camel ProducerTemplate possible memory leak -

-
To some degree, this is a bit of a shot in the dark, but we have a process that is dramatically slow One day's course we have found that all the things running on the fuses begin to draw, but when we are running a specific process, JPPropellers are going on, I have found that the increase in magnetic usage increases over time. . Org.apache.camel.ProductTemplate.Send So my main question is, is the way in which the manufacturer product is being used here which is wrong / can this be a problem? exchange foo = new DefaultExchange (getCamelContext (), ExchangePattern.InOnly); Foo.getIn () setBody (obj). Root R = Exchange .getContext (). GetRoute ("do_something_fun"); Creator Template Template = exchange.getContext () CreateProducerTemplate (); Template.send (r.getEndpoint (), foo); Generally, you should not create a productive template on each request as described here: / P> However, because I do not have a complete picture of your application, so you can cr...

javascript - Adhering to a max length setting with jshint -

-
I get several recommendations to compile a maximum of 80 characters when writing javascript, e.g. Google, NPM, Node. JS, Crockford In some cases, though, I do not think how best to do this. MongoClient.connect ('mongodb: // localhost: 27017 / sampleDatabase', function (mistake, database) {if (err)} {throw error;} db = database;}); This will throw a jshint warning because it exceeds 80 characters. Now, do you choose to ignore the warning in this example, or instead choose an option for a solution like MongoClient.connect ('mongodb: // localhost: 27017 / sampleDatabase' , Function (err, database) {if (err) {throw error;} db = database;}); If you can reuse the url variable So, great option if this is a shot, as is often such a call, I would probably do something like this ... / * jslint sloppy: true, white: true, browser: True, maxlen: 80 * / / * global mongo client * / var dbarhh, db; DbErrHand = function (mistake, database) {if (err) {throw error; } ...
