Answer : Yes, you can do it. An interface can extend multiple interfaces, as shown here: interface Maininterface extends inter1, inter2, inter3 { // methods } A single class can also implement multiple interfaces. What if two interfaces have a method defining the same name and signature? There is a tricky point: interface A { void test(); } interface B { void test(); } class C implements A, B { @Override public void test() { } } Then single implementation works for both :). Read my complete post here: http://codeinventions.blogspot.com/2014/07/can-interface-extend-multiple.html An interface can extend multiple interfaces . A class can implement multiple interfaces . However, a class can only extend a single class . Careful how you use the words extends and implements when talking about interface and class . Can an interface extend multiple interfaces in java? Answer is: Yes. According to JLS An interface ma

Answer : You seem to have got the XY problem. You have a task to solve, and instead of asking us about the task, you ask about a solution that you tried and already found inappropriate. Why do you want to apply the top property equal to half of element's height and negated? Because you want to move an absolutely positioned element half its height up . This is the original task. There's a simple solution to achieve that, and SASS is not even necessary! (Actually, as long as you don't know element's height, SASS can't provide more help than CSS.) We'll need an extra wrapper: <div class=container> <div class=elements-wrapper> <div class=element> </div> </div> </div> To push the element up for 50% of its height, do two simple steps: 1) Push its wrapper up fully out of the container: .elements-wrapper { position: absolute; bottom: 100%; } 2) Now pull the element down for 50% of its height: .ele

Answer : You're doing it right. The bound parameters are the one declared in a "prepared statement" using ?. Then they are bound using execute() with their value as a parameter to be bound to the statement. The protection comes from using bound parameters, not from using prepared statement Means it is not enough just to use prepare() but keep all variables in the query like this: $sql = $db->prepare("SELECT * FROM employees WHERE name ='$name'"); $sql->execute(); $rows = $sql->fetchAll(); Someone who said that meant "although technically you are using a prepared statement, you aren't binding variables to it". So it makes the query vulnerable all the same. To be protected, you have to substitute all variables in the query with placeholders, and then bind them: $sql = $db->prepare("SELECT * FROM employees WHERE name = ?"); $sql->bindParam(1, $name); $sql->execute(); $rows = $sql->fetchAll();

Answer : After this question was asked, Facebook launched HipHop for PHP which is probably the best-tested PHP compiler to date (seeing as it ran one of the world’s 10 biggest websites). However, Facebook discontinued it in favour of HHVM, which is a virtual machine, not a compiler. Beyond that, googling PHP compiler turns up a number of 3rd party solutions.

Example 1: how to automatically run queue in laravel for queues with no queue name i.e. queue name = default php artisan queue:work or php artisan queue:listen for jobs with a queue name. Let's assume i have a queue with name = sendemail php artisan queue:listen --queue=sendemail note: queue:work will only work for jobs entries currently in jobs table in database and stop. queue:listen will go on processing queues continously, both for current and new entries. Example 2: start laravel queue php artisan queue:work --queue=high,default

Answer : There are some solutions, make sure to check them all :) The router outlet will emit the activate event any time a new component is being instantiated, so we could use (activate) to scroll (for example) to the top: app.component.html <router-outlet (activate)="onActivate($event)" ></router-outlet> app.component.ts onActivate(event) { window.scroll(0,0); //or document.body.scrollTop = 0; //or document.querySelector('body').scrollTo(0,0) ... } Use, for exemple, this solution for a smooth scroll: onActivate(event) { let scrollToTop = window.setInterval(() => { let pos = window.pageYOffset; if (pos > 0) { window.scrollTo(0, pos - 20); // how far to scroll on each step } else { window.clearInterval(scrollToTop); } }, 16); } If you wish to be selective, say not every component should trigger the scrolling, you can

Answer : I don't think you can do this in Safari on the iPhone but you could use a 3rd party browser app. Many of those will let you set the browser agent. One browser I know does this is 'Atomic Web Browser'. This may not work in all cases as some websites may use other ways of determining which content to show, for example, some will detect the screen dimensions. I've tried this on my iPhone with Atomic Web Browser. Within the browser, I went to settings, 'Identify browser as' and selected 'Safari Desktop'. Then I went to nascar.com and tapped on the nascar logo. It showed me the desktop version of the page. I checked in mobile safari and doing the same indeed took me to a mobile version. An additional recommendation: the free Puffin browser in the App Store displays full websites. Google Chrome for iPhone is my daily driver for Stackexchange and it works wonderfully well both in desktop and mobile modes. Tap the menu button Reqest Desk

Answer : I had the same problem. I use idea 2017.2 and gradle 4.1, and some blog said you should add: dependencies { optional "org.springframework.boot:spring-boot-configuration-processor" } But I changed it to this: dependencies { compile "org.springframework.boot:spring-boot-configuration-processor" } And the warning is gone. According to the Spring Boot docs, the correct configuration since Gradle 4.6 is dependencies { annotationProcessor group: 'org.springframework.boot', name: 'spring-boot-configuration-processor' // ... } IntelliJ IDEA supports annotationProcessor scope since build 193.3382 (2019.3). Don't forget to enable annotation processing in IntelliJ IDEA settings. It happens to me for two reasons in IDEA: Double check if your setting is picked (enabled) in IDEA: Preferences->Annotation Processors->Enable annotation processing. After update your Idea, check your plugins and update them. It happens that plugin

Answer : Given in MDN, fromEntries() is available since Node v12: const map1 = new Map([ ['foo', 'bar'], ['baz', 42] ]); const obj = Object.fromEntries(map1); // { foo: 'bar', baz: 42 } For converting object back to map: const map2 = new Map(Object.entries(obj)); // Map(2) { 'foo' => 'bar', 'baz' => 42 } I hope this function is self-explanatory enough. This is what I used to do the job. /* * Turn the map<String, Object> to an Object so it can be converted to JSON */ function mapToObj(inputMap) { let obj = {}; inputMap.forEach(function(value, key){ obj[key] = value }); return obj; } JSON.stringify(returnedObject) You could loop over the map and over the keys and assign the value function createPaths(aliases, propName, path) { aliases.set(propName, path); } var map = new Map(), object = {}; createPaths(map, 'paths.aliases.server.entry', 'src/test'); createPaths(ma

Answer : I've found the solution by myself, to add a custom field after the serialization has been done we've to create a listener class like this: <?php namespace Acme\DemoBundle\Listener; use JMS\DiExtraBundle\Annotation\Service; use JMS\DiExtraBundle\Annotation\Tag; use JMS\DiExtraBundle\Annotation\Inject; use JMS\DiExtraBundle\Annotation\InjectParams; use Symfony\Component\HttpKernel\Event\PostResponseEvent; use Acme\DemoBundle\Entity\Team; use JMS\Serializer\Handler\SubscribingHandlerInterface; use JMS\Serializer\EventDispatcher\EventSubscriberInterface; use JMS\Serializer\EventDispatcher\PreSerializeEvent; use JMS\Serializer\EventDispatcher\ObjectEvent; use JMS\Serializer\GraphNavigator; use JMS\Serializer\JsonSerializationVisitor; /** * Add data after serialization * * @Service("acme.listener.serializationlistener") * @Tag("jms_serializer.event_subscriber") */ class SerializationListener implements EventSubscriberInterface { /**
