35,775,405 | Is there any use for basic_string<T> where T is not a character type? | <p>The declaration of C++ string <a href="http://en.cppreference.com/w/cpp/string/basic_string" rel="noreferrer">is the following</a>:</p>
<pre><code>template<
class CharT,
class Traits = std::char_traits<CharT>,
class Allocator = std::allocator<CharT>
> class basic_string;
</code></pre>
<p>The <code>CharT</code> is character type which can be <code>char</code>, <code>wchar_t</code>, <code>char16_t</code> and <code>char32_t</code>; but after all <code>basic_string</code> is a template so can be instantiated with other <code>CharT</code> and other allocators. While I can think in some use cases for other allocators I'm unable to think in use cases for strings of other data types, for example:</p>
<pre><code>using string = std::basic_string<int>;
</code></pre>
<p>Using a string of integers, we cannot initialize it as a string (obvious) nor u32 string (not that obvious, at least for me); but we can initialize it with <code>initializer_list</code> as long as the contained type of the list is convertible to <code>int</code>:</p>
<pre><code>string err1("test"); // Error!
string err2(U"test"); // Error!
string err3{"test"}; // Error!
string err4{U"test"}; // Error!
string err5 = "test"; // Error!
string err6 = U"test"; // Error!
string success1({U't', U'e', U's', U't'});
string success2 = {U't', U'e', U's', U't'};
string success3({'t', 'e', 's', 't'});
string success4 = {'t', 'e', 's', 't'};
</code></pre>
<p>But even if we manage to initialize a integer string, we cannot use it in the normal way:</p>
<pre><code>std::cout << success1; // Error! expected 116101115116
</code></pre>
<p>The only <code>basic_string</code> expected to be used with <code>cout</code> are the <em>normal</em> ones, that makes sense: after all we cannot assume how is supposed to be printed a string of integers or a string of <code>MyFancyClass</code>es.</p>
<p>But anyways, the creation of <em>strange</em> instances of <code>basic_string</code> isn't forbidden; on one hand is not forbidden due to the lack of features which forbids that use (a.k.a. concepts) and on the other coding <code>basic_string</code> without limiting the underlying type is easier than doing it on the opposite way (without concepts) so, that makes me wonder:</p>
<ul>
<li>Is there any use for <code>std::basic_string<T></code> where <code>T</code> is not a character type?</li>
</ul>
<p>As for <em>any use</em> I'm thinking about things that only can be achieved with strings of <code>T</code> and that cannot be done with vector of <code>T</code> (or it will be significantly harder to do), in other words:</p>
<ul>
<li>Have you ever faced a situation where a string of <code>T</code> is the better choice?</li>
</ul>

35,777,991 | TypeError: Super expression must be null or a function, not undefined with Babeljs | <p>I'm currently trying to make multiple-files inheritance in ES6, with node.JS and Babel (I'm using Babel to convert the code from ES6 to ES5 'cause Node don't implement ES6 right now).
I'm using import/export to "link" the differents files.</p>
<p>Actually I have :
<strong>Parent Class (File 1)</strong></p>
<pre><code>export class Point
{
constructor(x, y)
{
this.x = x;
this.y = y;
}
toString() {
return '(' + this.x + ', ' + this.y + ')';
}
}
</code></pre>
<p>And :
<strong>Child Class (File 2)</strong></p>
<pre><code>import Point from './pointES5'
export class ColorPoint extends Point
{
constructor(x, y, color)
{
super(x, y);
this.color = color;
}
toString() {
return super.toString() + ' in ' + this.color;
}
}
</code></pre>
<p>And the main
<strong>Main (File 3)</strong></p>
<pre><code>import Point from './pointES5'
import ColorPoint from './colorpointES5'
var m_point = new Point();
var m_colorpoint = new ColorPoint();
console.log(m_point.toString());
console.log(m_colorpoint.toString());
</code></pre>
<p>I'm doin' that to test the toString() methods calls, from Parent and from Child.<br>
So then I use Babel to convert the code from ES6 to ES5 and I run each parts separately to test if it's ok or not.<br>
- Point (the Parent) is good, and execute without error.<br>
- ColorPoint (the Child) don't run completely and throw : </p>
<blockquote>
<p>TypeError: Super expression must either be null or a function, not undefined</p>
</blockquote>
<p>The first line of the StackTrace is :</p>
<blockquote>
<p>function _inherits(subClass, superClass) { if (typeof superClass !== 'function' && superClass !== null) { throw new TypeError('Super expression must either be null or a function, not ' + typeof superClass); } subClass.prototype = Object.create(superClass && superClass.prototype, { constructor: { value: subClass, enumerable: false, writable: true, configurable: true } }); if (superClass) Object.setPrototypeOf ? Object.setPrototypeOf(subClass, superClass) : subClass.<strong>proto</strong> = superClass; }
(It comes from the ES5 converted code (Babelified), and I can post it entirely if it's needed).</p>
</blockquote>
<p>It is frustrating cause this code is very simple...
But I don't see what is causing the error.</p>
<p>I try differents versions of Babel (5, 5.8, 6) but there is no differences...</p>
<p>What have I done wrong ?</p>
<p>PS : I forgot to tell : it WORKS PERFECTLY when I do that in just one file. But it's really important to me to have only one class by file...</p>

<p>The problem with this version is that you have to get the entire file before sending it, which is not great, especially if it's something large like a video.</p>
<p>This version will directly stream the file:</p>
<pre><code>function(req,res){
var s3 = new AWS.S3();
s3.getObject({Bucket: myBucket, Key: myFile})
.createReadStream()
.pipe(res);
}
</code></pre>
<p>But unlike the first one, it won't do anything about the headers, which a browser might need to properly handle the file.</p>
<p>Is there a way to get the best of both worlds, passing through the correct headers from S3 but sending the file as a stream? It could be done by first making a <code>HEAD</code> request to S3 to get the metadata, but can it be done with one API call?</p>

It seems like C# always has 2 types of modifiers wherever C++ had one. For example, in C++ there is <code>&</code> for references and then in C# there is <code>ref</code> and <code>out</code> and I have to learn the subtle differences between them. Same with <code>readonly</code> and <code>const</code>, which are the topic of this thread. Can someone explain to me what the subtle differences are between the 2? Maybe show me a situation where I accidentally use the wrong one and my code breaks. </p>

<p>What about if we do something like <code>i=0</code> , <code>i++</code>, <code>i<= something</code> in a loop.Then i think it would be more readable and maintainable. </p>

35,815,928 | Why can't I declare a thread in an if in C++? Is there a way around? | <p>I am trying to use threading in an if statement. </p>
<p>The following code gives an error saying t1 in t1.join is not declared in this scope. Is there a way to make the loop skip the first thread operation and start multithreading for the other passes?</p>
<pre><code> #include <thread>
void someFunction() {/*someTask*/}
void main() {
bool isFirstRun = true;
while(true){
if(isFirstRun==false){std::thread t1(someFunction);}
//some long task
if(isFirstRun==false){t1.join}
if(isFirstRun){isFirstRun = false;}
}
}
</code></pre>
<p>More generally, is there a way to create a thread like a global variable in C++ and control its execution anywhere in the code? I saw the following in java and thought this might solve my problem if implemented in C++:</p>
<pre><code>Thread t1 = new Thread(new EventThread("e1"));
//some tasks here
t1.start();
//some tasks here
t1.join();

35,817,239 | Dependency injection with abstract class and object in Play Framework 2.5 | <p>I'm trying to migrate from Play 2.4 to 2.5 avoiding deprecated stuff.</p>
<p>I had an <code>abstract class Microservice</code> from which I created some objects. Some functions of the <code>Microservice</code> class used <code>play.api.libs.ws.WS</code> to make HTTP requests and also <code>play.Play.application.configuration</code> to read the configuration.</p>
<p>Previously, all I needed was some imports like:</p>
<pre><code>import play.api.libs.ws._
import play.api.Play.current
import play.api.libs.concurrent.Execution.Implicits.defaultContext
</code></pre>
<p>But now you <a href="https://www.playframework.com/documentation/2.5.x/ScalaWS">should use dependency injection to use <code>WS</code></a> and also <a href="https://www.playframework.com/documentation/2.5.x/Migration25#Deprecated-play.Play-and-play.api.Play-methods">to use access the current Play application</a>.</p>
<p>I have something like this (shortened):</p>
<pre><code>abstract class Microservice(serviceName: String) {
// ...
protected lazy val serviceURL: String = play.Play.application.configuration.getString(s"microservice.$serviceName.url")
// ...and functions using WS.url()...
}
</code></pre>
<p>An object looks something like this (shortened):</p>
<pre><code>object HelloWorldService extends Microservice("helloWorld") {
// ...
}
</code></pre>
<p>Unfortunately I don't understand how I get all the stuff (WS, configuration, ExecutionContect) into the abstract class to make it work.</p>
<p>I tried to change it to:</p>
<pre><code>abstract class Microservice @Inject() (serviceName: String, ws: WSClient, configuration: play.api.Configuration)(implicit context: scala.concurrent.ExecutionContext) {
// ...
}
</code></pre>
<p>But this doesn't solve the problem, because now I have to change the object too, and I can't figure out how.</p>
<p>I tried to turn the <code>object</code> into a <code>@Singleton class</code>, like:</p>
<pre><code>@Singleton
class HelloWorldService @Inject() (implicit ec: scala.concurrent.ExecutionContext) extends Microservice ("helloWorld", ws: WSClient, configuration: play.api.Configuration) { /* ... */ }
</code></pre>
<p>I tried all sorts of combinations, but I'm not getting anywhere and I feel I'm not really on the right track here.</p>
<p>Any ideas how I can use things like WS the proper way (not using deprecated methods) without making things so complicated?</p>

35,818,308 | Concept of creating Array of structures in C with three properties | <p>Hi all what I wish to create is some code in C that will allow me to store R,G,B values separately (this will be from an image), I have done some research and assume that using Array of structures to be the best way but still unsure. I then wish to access values from these structures to carry out some simple calculations. The problem I am having is getting my head around accessing the structure/arrays. I'm finding the conceptual part quite difficult if anyone can use a simple example it doesn't have to be relevant to my task but some sample code 3 properties to one structure would be helpful showing how the values can be accessed. I am also looking to understand how I load the structure with values. Any tips or help would be appreciated.</p>

<p>The Speed of Sound
The following table shows the approximate speed of sound in air, water, and steel:
Medium Speed
Air 1,100 feet per second
Water 4,900 feet per second
Steel 16,400 feet per second
Write a program that asks the user to enter “air”, “water”, or “steel”, and the distance that
a sound wave will travel in the medium. The program should then display the amount of
time it will take. You can calculate the amount of time it takes sound to travel in air with
the following formula:
Time 5 Distance / 1,100
You can calculate the amount of time it takes sound to travel in water with the following formula:
Time 5 Distance / 4,900
You can calculate the amount of time it takes sound to travel in steel with the following formula:
Time 5 Distance / 16,400</p>
