4. Dependency Injection
When you configure services and actions for your application, defining the dependency of your class is one of the core tasks. This chapter demonstrates various dependency injection options provided by parsley.
The preferred dependency configuration style is to use the as3 metadata tag, because the dependency of a class is the core part of the class definition. It makes sense to define the dependency of the class itself. In some cases, you may still prefer to declare depe
customize the operation through the proxy to achieve the same effect as the sub-class object body.Second: Event listener, the agent object listens to some important events of the object body, makes a specific response to the event or broadcasts the event to the object that needs to respond.The advantages of a personal understanding of the use of a delegation model are:1.

A delegate Declaration defines a type, which uses a specific set of parameters and the return type encapsulation method.
For static methods, the delegate object encapsulates the methods to be called.
For instance methods, the delegate object encapsulates an instance and a method on the instance at the same time.
If you have a delegate object and a set of appropriate parameters, you can use these parameters to call the delegate.
