Graph In computer science, a graph is an abstract data type that is meant to implement the undirected graph and directed graph concepts from mathematics. A graph data structure consists of a finite (and possibly mutable) set of vertices or nodes or points, together with a set of unordered pairs of...

Scala supports lazy evaluation for function arguments using notation: def func(arg: => String). Such function argument might take regular String object or a higher order function with String return type. In second case, function argument would be evaluated on value access. Please see the example...

Following points are to be kept in mind always: Take the PRD (Product Requirement Document from Business Analyst/Project Manager). If they don't have it, insist on a documentation since that will be the bible for your testing Once you get it, make sure to read it thoroughly. You will get comple...

Internally, Django uses the Python logging system. There is many way to configure the logging of a project. Here is a base: LOGGING = { 'version': 1, 'disable_existing_loggers': False, 'formatters': { 'default': { 'format': "[%(asctime)s] %(levelname)s [%(n...

In this example, we create an empty index (we index no documents in it) by defining its mapping. First, we create an ElasticSearch instance and we then define the mapping of our choice. Next, we check if the index exists and if not, we create it by specifying the index and body parameters that cont...

extension Dictionary { func merge(dict: Dictionary<Key,Value>) -> Dictionary<Key,Value> { var mutableCopy = self for (key, value) in dict { // If both dictionaries have a value for same key, the value of the other dictionary is used. mu...

See Ellie for a working example. This example uses the NoRedInk/elm-decode-pipeline module. Given a list of JSON objects, which themselves contain lists of JSON objects: [ { "id": 0, "name": "Item 1", "transactions": [ { "id&quo...

You can create a new paint with one of these 3 constructors: new Paint() Create with default settings new Paint(int flags) Create with flags new Paint(Paint from) Copy settings from another paint It is generally suggested to never create a paint object, or any other object in onDraw() as it ...

Text drawing settings setTypeface(Typeface typeface) Set the font face. See Typeface setTextSize(int size) Set the font size, in pixels. setColor(int color) Set the paint drawing color, including the text color. You can also use setARGB(int a, int r, int g, int b and setAlpha(int alpha) setLet...

setStyle(Paint.Style style) Filled shape FILL, Stroke shape STROKE, or both FILL_AND_STROKE setColor(int color) Set the paint drawing color. You can also use setARGB(int a, int r, int g, int b and setAlpha(int alpha) setStrokeCap(Paint.Cap cap) Set line caps, either ROUND, SQUARE, or BUTT (none)...

You can set the following flags in the constructor, or with setFlags(int flags) Paint.ANTI_ALIAS_FLAG Enable antialiasing, smooths the drawing. Paint.DITHER_FLAG Enable dithering. If color precision is higher than the device's, this will happen. Paint.EMBEDDED_BITMAP_TEXT_FLAG Enables the use o...

Indeed ,it is the Spring Data JPA module that makes it so easy to set up Pagination in a Spring boot app in the first place. Scenario expose an endpoint /students/classroom/{id} . It wi...

A program can easily waste time by calling a processor-intensive function multiple times. For example, take a function which looks like this: it returns an integer if the input value can produce one, else None: def intensive_f(value): # int -> Optional[int] # complex, and time-consuming cod...

In a basic implementation the task module must define a run/1 function that takes a list of arguments. E.g. def run(args) do ... end defmodule Mix.Tasks.Example_Task do use Mix.Task @shortdoc "Example_Task prints hello + its arguments" def run(args) do IO.puts "Hello ...

Presumably, your program will do something. Add your working code to the project in place of Program.fs. In this case, our task is to draw spirograph curves on a Window Canvas. This is accomplished using Spirograph.fs, below. namespace Spirograph // open System.Windows does not automatically o...

The XAML file for the spirograph parameters is below. It includes three text boxes for the spirograph parameters and a group of three radio buttons for color. When we give radio buttons the same group name - as we have here - WPF handles the on/off switching when one is selected. <!-- This fi...

go get downloads the packages named by the import paths, along with their dependencies. It then installs the named packages, like 'go install'. Get also accepts build flags to control the installation. go get github.com/maknahar/phonecountry When checking out a new package, get creates the ta...
