overloading

问题 There is a WebView which loads mobile-optimized URL (webpage). But when I click on a link, it does not load inside of the WebView (inside of the app), but mobile browser opens. How to prevent this? I tried overloading URLs via shouldOverrideUrlLoading() , but it did not help. This is a code. webView = (WebView) findViewById(R.id.webview); WebSettings webSettings = webView.getSettings(); webSettings.setPluginsEnabled(true); if (Build.VERSION.SDK_INT > 7) { webSettings.setPluginState

问题 Hi i want to do the following. I simply want to overload the [] method in order to access the instance variables... I know, it doesn't make great sense at all, but i want to do this for some strange reason :P It will be something like this... class Wata attr_accessor :nombre, :edad def initialize(n,e) @nombre = n @edad = e end def [](iv) self.iv end end juan = Wata.new('juan',123) puts juan['nombre'] But this throw the following error: overload.rb:11:in `[]': undefined method 'iv' for #

问题 I have a follow-on question to the problem that the presence of overloaded method definitions with and without parameters leads to a compilation error, which is already discussed here: Why is this reference ambiguous? To recap: trait A { def foo( s: String ) : String def foo : String = foo( "foo" ) } object B extends A { def foo( s: String ) : String = s } B.foo // won't compile results in the error message: error: ambiguous reference to overloaded function both method foo in object B of type

问题 Is there a way to overload functions in node.js similar to __noSuchMethod__ ? 回答1: Like bxjx briefly mentioned, Node.js is based on Google's V8 javascript engine, meaning that any language constructs or features come from that. Seeing as it is non-standard, i don't think they will add it in the near future. Also i don't think Node will ever base itself on a non-official V8 fork, but who knows. You can still use that fork yourself. 回答2: That would be cool. It would open up DSL like

问题 I am re-writing some code to make functional changes and I am stuck at a situation where either I will need to overload a function to accommodate two or three types of parameters (but performing almost identical operations on them) OR use one function with a lot of parameters. Now I am going with the latter option, and I just wanted to know specific disadvantages (if any) of using a function with a lot of parameters (and when I say lot, I mean 15). I am looking for a general answer, nothing

问题 When calling a generic method for storing an object there are occasionally needs to handle a specific type differently. I know that you can't overload based on constraints, but any other alternative seems to present its own problems. public bool Save<T>(T entity) where T : class { ... some storage logic ... } What I would LIKE to do is something like the following: public bool Save<SpecificClass>(T entity) { ... special logic ... } In the past our team has created 'one-off' methods for saving

问题 Assume that you have a Python (>=2.6) class with plenty (hundreds!) of methods. Now someone wants to subclass that but realized that most of the base class methods needs only some simple 'tuning'. Also there are only handful of different ways to tune those methods. Some involving input transformations, some output transformations, some both. To be more specific I'm looking for a (simple) solution for the inheritance where I just could provide the base class and a list (of lists) of methods to

问题 This question already has answers here : Closed 7 years ago . Possible Duplicate: Functions with const arguments and Overloading I am pretty confused by the overloading and const declaration rules. Here are two things that puzzle me maybe you can help me find the deeper misunderstanding in my head that result in them being puzzling to me. ;) First issue: My compiler allows this: void f(int & x) { std::cout << "plain f" << std::endl; } void f(const int & x) { std::cout << "const f" << std:

问题 I'm trying to call one of my methods from main but I'm getting an error message: No overload for method "NextImageName" takes 0 arguments Not sure how to fix this On my main I called for my method "BuildingBlock.NextImage();" This is where I get an error message. class BuildingBlock { public static string ReplaceOnce(string word, string characters, int position) { word = word.Remove(position, characters.Length); word = word.Insert(position, characters); return word; } public static string

问题 I'd like to comb off the n largest extremes from a timeseries. heapq works perfectly for the nlargest def nlargest(series, n): count = 0 heap = [] for e in series: if count < n: count+=1 hp.heappush(heap, e) else: # keeps heap size fixed hp.heappushpop(heap,e) ''' note: heap[0] is smallest ''' return heap but what about the n smallest? Note that i want a subset of the original series, so heapify and reversing the order won't work. What I'd like is essentially to overload the comparison
