PHP 5.x5.4 When you build REST API's, you may need to reduce the information of an object to be passed to the client application. For this purpose, this example illustrates how to use the JsonSerialiazble interface. In this example, the class User actually extends a DB model object of a hypotetica...

[JsonObject("person")] public class Person { [JsonProperty("name")] public string PersonName { get; set; } [JsonProperty("age")] public int PersonAge { get; set; } [JsonIgnore] public string Address { get; set; } } Person person = new...

We can use the Service Container as a Dependency Injection Container by binding the creation process of objects with their dependencies in one point of the application Let's suppose that the creation of a PdfCreator needs two objects as dependencies; every time we need to build an instance of PdfCr...

Consider the following example assuming that you have a ';'-delimited CSV to load into your database. 1;max;male;manager;12-7-1985 2;jack;male;executive;21-8-1990 . . . 1000000;marta;female;accountant;15-6-1992 Create the table for insertion. CREATE TABLE `employee` ( `id` INT NOT NULL , ...

A common usecase for the ready() hook is to access the DOM, e.g. to initiate a Javascript plugin, get the dimensions of an element etc. The problem Due to Vue's asynchronous DOM update mechanism, it's not guaranteed that the DOM has been fully updated when the ready() hook is called. This usually ...

In this example we show how to generate a simple sine wave, and output it on the user's speakers/headphones. let audioContext = new (window.AudioContext || window.webkitAudioContext)(); let sourceNode = audioContext.createOscillator(); sourceNode.type = 'sine'; sourceNode.frequency.value = 261...

Effects can be applied to audio by chaining nodes between the source and the destination node. In this example we use a gain node to mute the source, and only let sound through at specific times. This allows us to create morse code. function morse(gainNode, pattern) { let silenceTimeout = 300; ...

Assuming we want to modify bit n of an integer primitive, i (byte, short, char, int, or long): (i & 1 << n) != 0 // checks bit 'n' i |= 1 << n; // sets bit 'n' to 1 i &= ~(1 << n); // sets bit 'n' to 0 i ^= 1 << n; // toggles the value of bit 'n' Us...

Since Matlab R2014b it is easily possible to achieve semi-transparent markers for line and scatter plots using undocumented features introduced by Yair Altman. The basic idea is to get the hidden handle of the markers and apply a value < 1 for the last value in the EdgeColorData to achieve the d...

Sometimes it is useful to create union types with only one case to implement record-like types: type Point = Point of float * float let point1 = Point(0.0, 3.0) let point2 = Point(-2.5, -4.0) These become very useful because they can be decomposed via pattern matching in the same way as tu...

Singleton Objects Scala supports static members, but not in the same manner as Java. Scala provides an alternative to this called Singleton Objects. Singleton objects are similar to a normal class, except they can not be instantiated using the new keyword. Below is a sample singleton class: object...

Array.prototype.map(): Returns a new array with the results of calling a provided function on every element in the original array. The following code example takes an array of persons and creates a new array containing persons with a 'fullName' property var personsArray = [ { id: 1, f...

In JavaScript all arguments are passed by value. When a function assigns a new value to an argument variable, that change will not be visible to the caller: var obj = {a: 2}; function myfunc(arg){ arg = {a: 5}; // Note the assignment is to the parameter variable itself } myfunc(obj); conso...

string outsidetext = "I am outside of bracket"; string.Format("{{I am in brackets!}} {0}", outsidetext); //Outputs "{I am in brackets!} I am outside of bracket"

Example : CLLocationManager *locationManager = [[CLLocationManager alloc] init]; locationManager.delegate = self; locationManager.desiredAccuracy = kCLLocationAccuracyBest; locationManager.distanceFilter = 5; E.g. In the above example code above, location changes of less than 5 m...

Firstly, include the ngStorage source in your index.html. An example injecting ngStorage src would be: <head> <title>Angular JS ngStorage</title> <script src = "http://ajax.googleapis.com/ajax/libs/angularjs/1.3.14/angular.min.js"></script> &l...

Any permission required by your application to access a protected part of the API or to interact with other applications must be declared in your AndroidManifest.xml file. This is done using the <uses-permission /> tag. Syntax <uses-permission android:name="string" android...

Collection initialization syntax can be used when instantiating any class which implements IEnumerable and has a method named Add which takes a single parameter. In previous versions, this Add method had to be an instance method on the class being initialized. In C#6, it can also be an extension me...

Open Control Panel -> Programs and Features, choose the Visual Studio 2015 item, and then choose the Change button. In the setup wizard for Visual Studio, choose the Modify button. In the list of optional features to install, select the HTML/JavaScript (Apache Cordova) checkbox, c...
