Here is a class (Dog) creating its own dependency (Food):
class Dog {
public Dog() {
var food = new Food();
this.eat(food);
}
}
Here is the same class being injected with its dependency using constructor injection:
class Dog {
public Dog(Food food) {

HBase Standalone is a mode which allow you to get rid of HDFS and to test HBase before deploying in a cluster, It is not production oriented.
Installing HBase in standalone is extremely simple. First you have to download the HBase archive named hbase-X.X.X-bin.tar.gz available on one of the apache ...
If you only need a given resource for a specific control, you can make it more local by adding it to this specific control, instead of the window. It works exactly the same way, the only difference being that you can now only access from inside the scope of the control where you put it:
<StackPa...
In this example, we'll be accessing three different resources from Code-behind, each stored in a different scope
App.xaml:
<Application x:Class="WpfSamples.App"

If you need to send events from fragment to activity, one of the possible solutions is to define callback interface and require that the host activity implement it.
Example
Send callback to an activity, when fragment's button clicked
First of all, define callback interface:

This is an example for how to handle dynamic key for response. Here A and B are dynamic keys it can be anything
Response
{
"response": [
{
"A": [
{
"name": "Tango"
},
{
"name": "P...
You can use the $q.all function to call a .then method after an array of promises has been successfully resolved and fetch the data they resolved with.
Example:
JS:
$scope.data = []
$q.all([
$http.get("data.json"),
$http.get("more-data.json"),
]).then(funct...

If you want to provide a URL out of convenience for your user but map it directly to another one you're already using. Use a redirect:
# config/routes.rb
TestApp::Application.routes.draw do
get 'courses/:course_name' => redirect('/courses/%{course_name}/lessons'), :as => "course"...
The basic math operations are performed mainly on numbers or on vectors (lists of numbers).
1. Using single numbers
We can simple enter the numbers concatenated with + for adding and - for subtracting:
> 3 + 4.5
# [1] 7.5
> 3 + 4.5 + 2
# [1] 9.5
> 3 + 4.5 + 2 - 3.8
# [1] 5.7

There are two possible ways to pass a value type by reference: ref and out. The difference is that by passing it with ref the value must be initialized but not when passing it with out. Using out ensures that the variable has a value after the method call:
public void ByRef(ref int value)
{
C...
curl -XGET http://www.example.com:9200/myIndexName/_search?pretty=true&q=*:*
This uses the Search API and will return all the entries under index myIndexName.

Imagine you have all dates in all responses in some custom format, for instance /Date(1465935152)/ and you want apply general rule to deserialize all Json dates to java Date instances. In this case you need to implement custom Json Deserializer.
Example of json:
{
"id": 1,

For example, types for SI units have been standardized in the F# core library, in Microsoft.FSharp.Data.UnitSystems.SI. Open the appropriate sub-namespace, UnitNames or UnitSymbols, to use them. Or, if only a few SI units are required, they can be imported with type aliases:
/// Seconds, the SI uni...
All values in Rust have exactly one owner. The owner is responsible for dropping that value when it goes out of scope, and is the only one who may move the ownership of the value. The owner of a value may give away references to it by letting other pieces of code borrow that value. At any given time...
All values in Rust have a lifetime. A value's lifetime spans the segment of code from the value is introduced to where it is moved, or the end of the containing scope
{
let x = String::from("hello"); // +
// ... :
let y = S...
Most of the questions around ownership come up when writing functions. When you specify the types of a function's arguments, you may choose how that value is passed in. If you only need read-only access, you can take an immutable reference:
fn foo(x: &String) {
// foo is only authorized to...
Some Rust types implement the Copy trait. Types that are Copy can be moved without owning the value in question. This is because the contents of the value can simply be copied byte-for-byte in memory to produce a new, identical value. Most primitives in Rust (bool, usize, f64, etc.) are Copy.
let x...
This example shows how to establish a connection to an SSL-enabled POP3 email server and send a simple (text only) email.
// Configure mail provider
Properties props = new Properties();
props.put("mail.smtp.host", "smtp.mymailprovider.com");
