The following class can be used as a single class that can handle GET, POST, PUT, PATCH, and other requests: class APIResponseObject{ int responseCode; String response; APIResponseObject(int responseCode,String response) { this.responseCode = responseCode; ...

When we attach the !important keyword to a mixin call, the Less compiler will automatically add the !important to all properties that are present within the mixin. For example, consider the below mixin: .set-default-props() { margin: 4px; padding: 4px; border: 1px solid black; font-wei...

I'll demonstrate the basic usage of using functions vs using labels+gosub. In this example we'll implement simple functionality to add two numbers and store them in a variable. With functions: c := Add(3, 2) ; function call MsgBox, Result: %c% Add(a, b) { ; This is a function. Put it wherever...

This script demonstrates how to receive complicated GUI events from different controls in the same event callback function. We'll be using two ListView controls for that. Now every time an action is detected on one of those ListView controls, we want a precise description of what happened and have ...

Haskell supports importing a subset of items from a module. import qualified Data.Stream (map) as D would only import map from Data.Stream, and calls to this function would require D.: D.map odd [1..] otherwise the compiler will try to use Prelude's map function.

Classes, structs, enums and all their methods are internal by default. This means they can be only accessed from the same module. The test cases are in a different target an this means they are in a different module. To be able to access the method you want to test, you need to import the module to ...

// Add observer let observer = NSNotificationCenter.defaultCenter().addObserverForName("nameOfTheNotification", object: nil, queue: nil) { (notification) in // Do operations with the notification in this block } // Remove observer NSNotificationCenter.defaultCenter().removeObser...

Lambda Expresions are an extension of anonymous methods that allow for implicitly typed parameters and return values. Their syntax is less verbose than anonymous methods and follows a functional programming style. using System; using System.Collections.Generic; using System.Linq; ...

Unlike a parallel for-loop (parfor), which takes the iterations of a loop and distributes them among multiple threads, a single program, multiple data (spmd) statement takes a series of commands and distributes them to all the threads, so that each thread performs the command and stores the results....

You can use the archivesBaseName to set the name of apk. For example: defaultConfig { .... project.ext.set("archivesBaseName", "MyName-" + defaultConfig.versionName); } You will obtain this output. MyName-X.X.X-release.apk

To remove all elements from a Map, use the .clear() method: map.clear(); Example: const map = new Map([[1, 2], [3, 4]]); console.log(map.size); // 2 map.clear(); console.log(map.size); // 0 console.log(map.get(1)); // undefined

To remove an element from a map use the .delete() method. map.delete(key); Example: const map = new Map([[1, 2], [3, 4]]); console.log(map.get(3)); // 4 map.delete(3); console.log(map.get(3)); // undefined This method returns true if the element existed and has been removed, otherwise fal...

To check if a key exists in a Map, use the .has() method: map.has(key); Example: const map = new Map([[1, 2], [3, 4]]); console.log(map.has(1)); // true console.log(map.has(2)); // false

To get the numbers of elements of a Map, use the .size property: const map = new Map([[1, 2], [3, 4]]); console.log(map.size); // 2

Using requestAnimationFrame may on some systems update at more frames per second than the 60fps. 60fps is the default rate if the rendering can keep up. Some systems will run at 120fps maybe more. If you use the following method you should only use frame rates that are integer divisions of 60 so th...

Here is a very simple example to illustrate how to write a NIF. Directory structure: nif_test ├── c_src │   ├── Makefile │   └── nif_test.c ├── rebar.config └── src ├── nif_test.app.src └── nif_test.erl This structure can be easily initialized using Rebar3: $ rebar3 new lib nif_...

var client = new AmazonDynamoDBClient(); // Store item client.PutItem(new PutItemRequest { TableName = "Books", Item = new Dictionary<string, AttributeValue> { { "Title", new AttributeValue { S = "Cryptonomicon" } }, { "...

var client = new AmazonDynamoDBClient(); Table booksTable = Table.LoadTable(client, "Books"); // Store item Document book = new Document(); book["Title"] = "Cryptonomicon"; book["Id"] = 42; book["Authors"] = new List<string> { "Ne...

This example consists of two parts: first, we must define our Book type; second, we use it with DynamoDBContext. [DynamoDBTable("Books")] class Book { [DynamoDBHashKey] public int Id { get; set; } public string Title { get; set; } public List<string> Authors { ...

Starting with Java 8, you can use lambda expressions & predicates. Example: Use a lambda expressions & a predicate to get a certain value from a list. In this example every person will be printed out with the fact if they are 18 and older or not. Person Class: public class Person { p...
