the application's dependency on the plug-in to be dispelled. You can also do this by using the service locator mode, and after discussing dependency injection we'll talk about service locator services location mode. the form of dependency injection The basic idea of dependency injection is that there is a separate object – an assembler, which obtains a field that implements the appropriate implementation class for the Finder interface and assigns it to the Movielister class. The current depende

libraries, we describe its dependent projects. During the run, an injector will create the dependent instances and pass them on to a dependent consumer.// A good example from the Angularjs function SomeClass (greeter) { this.greeter =function(name) { this. Greeter.greet (name) }Note: As with the instance code above, it is never a good idea to create a controller in the global scope. The code above simply simplifies the principle of depend

]; [Self. navigationController pushViewController: vc animated: YES]; } In this case, ViewControllerA needs to import ViewControllerB, that is, the dependency on ViewControllerB. The more dependent things, the more difficult it is to maintain, and the loop dependency problem may also occur. objection can handle these problems. The implementation method is: first define a protocol, and then register the class corresponding to this protocol through objection. When necessary, you can obtain the o

application has an injector (injector) to handle the creation of dependencies. An injector is a service locator that is responsible for locating and creating dependencies. As an example:Angular.module (' MyModule ', []). //tell the injector how to create this greeter //Note that the greeter itself relies on ' $window

When a type of instance is requested, the injector determines how to create an instance and parse dependencies Based on the object graph. To determine how to parse dependencies, you must configure the binding method of the injector. To create a binding object, you can inherit

How do I find the API?ANGULARJS provides some functionality for encapsulation, but when you try to access these features through the global object angular, you find that it is very different from the libraries you have encountered before.For example, Angularjs exposes a global object: angular, which also encapsulates an Ajax call, provides a $http object, but when accessing angular. $http, you can't find it.Dependency Injection/diIn fact, ANGULARJS organizes all of the functional components in a

as follows: The Code is as follows: Var doSomething = function (service, router, other ){Var s = service ();Var r = router ();}; In the above Code, we completely passed the required modules. However, this brings about a new problem. Suppose we call the doSomething method in the Code's brother. What should we do if we need the third dependency. In this case, it is not wise to edit all function call code. Therefore, we need a piece of code to help us do this. This is the problem that the depend

1. Module and Dependency Injection Overview 1. Understanding ModulesThe Angularjs module is a container that isolates code and organizes it into simple, neat, reusable blocks.The module itself does not provide direct functionality: an instance of an object that contains other functions: Controller, filter, service, animationYou can build a module by defining the object it provides. Connect modules together with dependency injection to build a complete application.The ANGULARJS is built on the pr

RequireJS/AMD MethodYou may have heard about RequireJS, which is a good choice for solving dependency injection.Copy codeThe Code is as follows:Define (['service', 'router '], function (service, router ){//...});This idea is to first describe the required dependencies and then write your function. The order of parameters is very important. As mentioned above, let's write a module called injector, which can accept the same synt

we need. We cannot write too many things-we need to streamline the beautiful syntax Injection should keep the scope of the passed Function The passed function should be able to accept custom parameters, not just dependency descriptions. A perfect list. Let's implement it below. RequireJS/AMD Method You may have heard about RequireJS, which is a good choice for solving dependency injection. Define (['service', 'router '], function (service, router ){ //... }); This idea is to first describe t

The dependencies between classes in an application can be very complex, created in a class instance, you need to first create an example of the class on which the class depends, and you create instances of the dependent classes, which may depend on other classes, and so on. So when you create a class instance, you are creating an object graph object. Creating object graph by hand is a tedious and error-prone process, and it's hard to test your code, and Guice or roboguice can help you create ob

The solution is to load $rootScope by $injector delay. The following code is only loaded when the $rootScope is first used. ? 1 2 3 4 5 6 7 8 9 10 11 12-13 $provide.

configuration (configuration) that executes blocks (blocks) that are applied in the process that initiates the application. In its simplest form, it consists of two class blocks: 1. Configuration block (configuration blocks): Performed during provider registration and configuration. Only provider and constant (constants?) ) can be injected (injected) into the configuration blocks. This is to avoid the occurrence of the service being executed before the service configuration is complete. 2. Ru
