This example just illustrates how this keyword can be used. int a = 10; // Assume that type of variable 'a' is not known here, or it may // be changed by programmer (from int to long long, for example). // Hence we declare another variable, 'b' of the same type using // decltype keyword. de...

Let's say we have vector: std::vector<int> intVector; And we want to declare an iterator for this vector. An obvious idea is to use auto. However, it may be needed just declare an iterator variable (and not to assign it to anything). We would do: vector<int>::iterator iter; Howev...

To influence property lookup, the get handler must be used. In this example, we modify property lookup so that not only the value, but also the type of that value is returned. We use Reflect to ease this. let handler = { get(target, property) { if (!Reflect.has(target, property)) { ...

File exists: Sub FileExists() Dim fso as Scripting.FileSystemObject Set fso = CreateObject("Scripting.FileSystemObject") If fso.FileExists("D:\test.txt") = True Then MsgBox "The file is exists." Else MsgBox "The file isn't exist...

F() expressions can be used to execute arithmetic operations (+, -, * etc.) among model fields, in order to define an algebraic lookup/connection between them. Let model be: class MyModel(models.Model): int_1 = models.IntegerField() int_2 = models.IntegerField() Now lets assum...

This example demonstrates the use of GET, POST, PUT and DELETE HTTP Methods in doing CRUD operations on a REST resource I am using the below software, frameworks and tools: Jersey 2.25.1 JDK 1.7.x (Java 7) Eclipse IDE Kepler Apache Maven 3.3.9 Apache Tomcat 7.x Please follow the below ste...

To have a look of the different functionalities of the hybris platform, you can use the install recipes. For this, just download the HYBRISCOMMXXXX_X-XXXXXXXX.ZIP and extract it to you local device. Than go through the following steps: The <recipe_names> you can find under the folder \hybris\...

In a terminal run brew install maven Once the install is over check that maven works correctly with mvn -v. The output should look something like: Apache Maven 3.3.9 Maven home: /usr/local/Cellar/maven/3.3.9/libexec Java version: 1.8.0_121, vendor: Oracle Corporation Java home: /Library/Ja...

Extracting all the files into a directory is very easy: using (FileStream fs = new FileStream("archive.zip", FileMode.Open)) using (ZipArchive archive = new ZipArchive(fs, ZipArchiveMode.Read)) { archive.ExtractToDirectory(AppDomain.CurrentDomain.BaseDirectory); } When the file...

For this example we will test the sum method of a simple calculator. In this example we will test the application: ApplicationToTest. This one has a class called Calc. This class has a method Sum(). The method Sum() looks like this: public void Sum(int a, int b) { return a + b; } The un...

Java Singleton Pattern To implement Singleton pattern, we have different approaches but all of them have following common concepts. Private constructor to restrict instantiation of the class from other classes. Private static variable of the same class that is the only instance of the class. P...

Lets assume that we have a complex api, with many generic views and some generic viewsets. We want to enable PageNumberPagination to every view, except one (either generic view or viewset, does not make a difference) for which we want a customized case of LimitOffsetPagination. To achieve that we n...

This example shows you how to implement proxy classes for your Minecraft Mod Application, which are used to initialize your mod. First of all you will need to implement the base CommonProxy.java class which contains the 3 mainly used method: public class CommonProxy { public void preInit(FMLP...

override func viewDidLoad() { super.viewDidLoad() // Do any additional setup after loading the view, typically from a nib. let imageView = UIImageView(frame: CGRect(x: CGFloat(0), y: CGFloat(50), width: CGFloat(320), height: CGFloat(320))) view.addSubview(imageVi...

multiply-square-matrix-parallel(A, B) n = A.lines C = Matrix(n,n) //create a new matrix n*n parallel for i = 1 to n parallel for j = 1 to n C[i][j] = 0 pour k = 1 to n C[i][j] = C[i][j] + A[i][k]*B[k][j] return C

matrix-vector(A,x) n = A.lines y = Vector(n) //create a new vector of length n parallel for i = 1 to n y[i] = 0 parallel for i = 1 to n for j = 1 to n y[i] = y[i] + A[i][j]*x[j] return y

Q-learning is a variant of model-free reinforcement learning. In Q-learning we want the agent to estimate how good a (state, action) pair is so that it can choose good actions in each state. This is done by approximating an action-value function (Q) that fits in equation below: Where s and a are ...
