In this example we have a service, let's call it search service that has a method called search() which will initiate a get request to a back end API. function SearchService($http) { const service = {}; service.search = function() { return $http({method: 'GET', url: `/api/s...

Unity layers are similar to tags as in that they can be used to define objects that should be interacted with or should behave in a certain manner, however, layers are mainly used with functions in the Physics class: Unity Documentation - Physics Layers are represented by an integer and can be pass...

The LayerMask structure is an interface that functions almost exactly like passing an integer to the function in question. However, its biggest benefit is allowing the user to select the layer in question from a drop-down menu in the inspector. using UnityEngine; class LayerMaskExample{ pub...

The following example code computes the sum of 1+4(3+3^2+3^3+3^4+...+3^N) series using pow() family of standard math library. #include <stdio.h> #include <math.h> #include <errno.h> #include <fenv.h> int main() { double pwr, sum=0; int i, n; ...

In Haskell, you can define any infix operator you like. For example, I could define the list-enveloping operator as (>+<) :: [a] -> [a] -> [a] env >+< l = env ++ l ++ env GHCi> "**">+<"emphasis" "**emphasis**" You should always give s...

Because infixes are so common in Haskell, you will regularly need to look up their signature etc.. Fortunately, this is just as easy as for any other function: The Haskell search engines Hayoo and Hoogle can be used for infix operators, like for anything else that's defined in some library. ...

If you've got multiple implementations of the same interface, Spring needs to know which one it should autowire into a class. I'm going to use a Validator pattern in this example.1 Foo Class: public class Foo { private String name; private String emailAddress; private String erro...

If you've got an interface with a generic type parameter, Spring can use that to only autowire implementations that implement a type parameter you specify. Interface: public interface GenericValidator<T> { public T validate(T object); } Foo Validator Class: @Component public class...
