methods

问题 I'm trying to return a value that i get from onResponse method in retrofit call request, is there a way that i can get that value out of the overrided method? here is my code: public JSONArray RequestGR(LatLng start, LatLng end) { final JSONArray jsonArray_GR; EndpointInterface loginService = ServiceAuthGenerator.createService(EndpointInterface.class); Call<GR> call = loginService.getroutedriver(); call.enqueue(new Callback<GR>() { @Override public void onResponse(Response<GR> response ,

问题 I found a great description of the semantic difference between Properties and Methods (paraphrased, via http://www.webdeveloper.com/forum/showthread.php?133712-Properties-Vs.-Methods): Properties are like nouns. They have a value or state. Methods are like verbs. They perform actions. A property can't perform an action and the only value that a method has is the one that is returned after it finishes performing the action. e.g. Property : door; Possible Values : open, closed Method : openDoor

问题 I am trying to verify the difference between instance attributes and class attributes as laid out by the Python tutorial release 2.7.3 dated Nov 01, 2012, chapter 9: Classes, Page 66 last line (source): Valid method names of an instance object depend on its class. By definition, all attributes of a class that are function objects define corresponding methods of its instances. So in our example, x.f is a valid method reference, since MyClass.f is a function, but x.i is not, since MyClass.i is

问题 When do I use @see when dealing with JavaDocs? What is its usage? For example if MethodA calls MethodB then do I have to put @see in MethodB 's javadoc and reference MethodA because that is what called it, or do I have to put a reference to MethodB from MethodA because it's calling it. I've read the stuff about @see on the Oracle website and it seems to me to be incredibly vague, it says it means "see also" but not really what that means! 回答1: Yeah, it is quite vague. You should use it

问题 On CodeReview I posted a working piece of code and asked for tips to improve it. One I got was to use a boolean method to check if an ArrayList had an even number of indices (which was required). This was the code that was suggested: private static boolean isEven(int number) { return (number & 1) == 0; } As I've already pestered that particular user for a lot of help, I've decided it's time I pestered the SO community! I don't really understand how this works. The method is called and takes

问题 In Scala one might define methods inside other methods. This limits their scope of use to inside of definition block. I use them to improve readability of code that uses several higher-order functions. In contrast to anonymous function literals, this allows me to give them meaningful names before passing them on. For example: class AggregatedPerson extends HashSet[PersonRecord] { def mostFrequentName: String = { type NameCount = (String, Int) def moreFirst(a: NameCount, b: NameCount) = a._2 >

问题 I've seen some discussions in SO and other places regarding how this should be or will be done in future versions of Roxygen2. However, I am stuck. How should I go about documenting a S4 generic, as well as its methods, using Roxygen2? A working example for a brand new generic/methods, as well as an example for extending base S4 generic would be incredibly useful. I do not want to have to make separate (mostly) redundant documentation for each S4 method of the same generic. Due dilligence: I

问题 After working a long time on an iPhone app, I realized that my code is quite dirty, containing several #import and methods that are not called or useful at all. I would like to know if there's any compiler directive or way to detect those useless lines of code. Does Xcode have any tool to detect this? 回答1: Xcode allows you to (un)check settings for specific compiler warnings that can warn you of some types of unused code. (Select the project in the source list and File > Get Info, then select

问题 For example, i use this code for testing routes: $app->get('/api', function () { echo 'get!'; }); $app->post('/api', function () { echo 'post!'; }); $app->put('/api', function () { echo 'put!'; }); For api testing i use RestClient plugin for Chrome. When i try do GET request, response is 'get!'. Its good. But: When i try do POST request, response also is 'get!'. Why? Its must be 'post!'. When i try do PUT request, (in Response Headers: Allow: GET,HEAD,POST,OPTIONS,TRACE ) Slim response have
