parameters

问题 It's absolutely strange, but I can't find any Java/Android URL parser that will be compatible to return full list of parameters. I've found java.net.URL and android.net.Uri but they are can't return parameters collection. I want to pass url string, e.g. String url = "http://s3.amazonaws.com/?AWSAccessKeyId=123&Policy=456&Signature=789&key=asdasd&Content-Type=text/plain&acl=public-read&success_action_status=201"; SomeBestUrlParser parser = new SomeBestUrlParser(url); String[] parameters =

问题 This question already has answers here : Closed 9 years ago . Possible Duplicate: What does the @ symbol before a variable name mean in C#? I have been coding in C# for about a year now, and recently i came across the following public bool OnPreUpdate(PreUpdateEvent @event) As you can see event has an '@' sign before it, is this just to prevent the compiler detecting it as the event type, therefore does '@' gets treated as any other text or is there a special meaning to it? 回答1: An @ sign

问题 The Google C++ Style Guide draws a clear distinction (strictly followed by cpplint.py) between input parameters(→ const ref, value) and input-output or output parameters (→ non const pointers) : Parameters to C/C++ functions are either input to the function, output from the function, or both. Input parameters are usually values or const references, while output and input/output parameters will be non-const pointers. And further : In fact it is a very strong convention in Google code that

问题 Here in fun swap I am trying to change the value of a1 with b1, but it shows "val cannot be reassigned compile time error" . If I can't change like this, then how is it possible to do? fun swap(a1: String, b1: String) { val temp = a1 a1 = b1 b1 = temp } Note: This is just a sample to know why I am not able to reassign the local variable as we can do in Java. 回答1: In Kotlin val declares final, read only, reference - and that is exactly what compiler error is telling you with Val cannot be

问题 When navigating to a new webpage, is there a "Best Practice" for passing Ids around. For example, a person registers to use a website, they get given an Id, this needs to be passed around the rest of the website/pages where it is used to retrieve relevant data from a database.

Putting this value in a

问题 I am trying to pass in a URL as a parameter to a TTURLMap like this: [map from@"tt://person/(initWithURL:)" toViewController: [PersonViewController class]]; I then have a TTStyledTableItemCell with links that render like this: <a href="tt://person/http://persons.url.com/blah">Person name</a> but when I click on these links the link doesn't call the initWithURL: method in the PersonViewConroller class. I've verified things are wired up correctly by passing in a simple string. I believe this

I'm using HttpClient on client-side and ServerFileUpload on server-side. This is the client-side code: ...

问题 Looking at the docs for the .each() function in jquery shows the following method signature: .each( function(index, Element) ) http://api.jquery.com/each/ I can understand needing to pass in an index so that it is available for use within the callback but why would you explicitly include the Element parameter if you can just reference the current element by the this keyword? Is it there just so that you can specify an instance name of your choice? I mean, if you still have to wrap a named
