Constructor overloading is not available in As3. In order to provide a different way to retrieve an instance of a class, a public static method can be provided to serve as an alternative "constructor". An example for that is flash.geom.Point, which represents a 2D point object. The coor...

When an extension method returns a value that has the same type as its this argument, it can be used to "chain" one or more method calls with a compatible signature. This can be useful for sealed and/or primitive types, and allows the creation of so-called "fluent" APIs if the me...

The Iterator.remove() method is an optional method that removes the element returned by the previous call to Iterator.next(). For example, the following code populates a list of strings and then removes all of the empty strings. List<String> names = new ArrayList<>(); names.add("...

It is very convenient to use extension methods with interfaces as implementation can be stored outside of class and all it takes to add some functionality to class is to decorate class with interface. public interface IInterface { string Do() } public static class ExtensionMethods{ pu...

dotimes is a macro for integer iteration over a single variable from 0 below some parameter value. One of the simples examples would be: CL-USER> (dotimes (i 5) (print i)) 0 1 2 3 4 NIL Note that NIL is the returned value, since we did not provide one ourselves; the v...

Method chaining is a programming strategy that simplifies your code and beautifies it. Method chaining is done by ensuring that each method on an object returns the entire object, instead of returning a single element of that object. For example: function Door() { this.height = ''; this.w...

In [1]: df1 = pd.DataFrame({'x': [1, 2, 3], 'y': ['a', 'b', 'c']}) In [2]: df2 = pd.DataFrame({'y': ['b', 'c', 'd'], 'z': [4, 5, 6]}) In [3]: df1 Out[3]: x y 0 1 a 1 2 b 2 3 c In [4]: df2 Out[4]: y z 0 b 4 1 c 5 2 d 6 Inner join: Uses the intersection ...

List doesn't support "random access", which means it takes more work to get, say, the fifth element from the list than the first element, and as a result there's no List.get nth list function. One has to go all the way from the beginning (1 -> 2 -> 3 -> 4 -> 5). If you need ra...

Arrays can have more than one dimension. The following example creates a two-dimensional array of ten rows and ten columns: int[,] arr = new int[10, 10]; An array of three dimensions: int[,,] arr = new int[10, 10, 10]; You can also initialize the array upon declaration: int[,] arr = new int...

A comment is marked by an apostrophe ('), and ignored when the code executes. Comments help explain your code to future readers, including yourself. Since all lines starting with a comment are ignored, they can also be used to prevent code from executing (while you debug or refactor). Placing an ap...

Sub RemComments() Rem Comments start with "Rem" (VBA will change any alternate casing to "Rem") Rem is an abbreviation of Remark, and similar to DOS syntax Rem Is a legacy approach to adding comments, and apostrophes should be preferred Rem Comments CANNOT appear af...

This is an example of how to use the generic type TFood inside Eat method on the class Animal public interface IFood { void EatenBy(Animal animal); } public class Grass: IFood { public void EatenBy(Animal animal) { Console.WriteLine("Grass was eaten by: {0}",...

.htaccess can be used to set a custom error pages that matches the theme of your website instead of seeing a white error page with black techno-babble when users end up on at a page with an error server response code. The error page can be any browser parseable file, including (But not limited to)...

Overload resolution partitions the cost of passing an argument to a parameter into one of four different categorizes, called "sequences". Each sequence may include zero, one or several conversions Standard conversion sequence void f(int a); f(42); User defined conversion seque...

If your class doesn't implement a specific overloaded operator for the argument types provided, it should return NotImplemented (note that this is a special constant, not the same as NotImplementedError). This will allow Python to fall back to trying other methods to make the operation work: When...

Start two named nodes in two terminal windows: >iex --name [email protected] iex([email protected])> >iex --name [email protected] iex([email protected])> Connect two nodes by instructing one node to connect: iex([email protected])> Node.connect :"[email protected]" true The two n...

Use the HTML or <audio> element to embed video/audio content in a document. The video/audio element contains one or more video/audio sources. To specify a source, use either the src attribute or the <source> element; the browser will choose the most suitable one. Audio tag example: &...
