Advice is the implementation of the cross-cutting functionality. An Adivce provides the code for implementation of the service.

There are four types of Advice:

• Before Advice
• After Advice
• Around Advice
• Throws Advice

As we know the Aspect is just the name of the cross-cutting functionality, not the implementation. So what’s the implementation of the cross-cutting functionality? It’s called Advice. An Advice provides the code for implementation of the service. It is like Logging service, Logging is a Aspect and Advice denotes the implementation of Log4j.

An Aspect represent the name of a cross-cutting functionality, it’s only name not implementation.

Let us see the example.

public class MyLogicClass
{
	public void logicOne() {

		//Call Transcation Service
		//Call Email Service
	}

	public void logicTwo() {
		//This is my logic for two.

		//Call Authentication Service 
		//Call Logging Service
		//Call Transcation Service
		//Call Email Service
	}
}

What is AOP?, AOP stand for Aspect Oriented Programming. It’s very important module for Spring framework. In the enterprise level application programming we used to add different types of services to our application at runtime automatically, like logging, email, transaction, authentication services. These actions we called cross-cutting functionalities. AOP do this job.

The call() function is a fantastic method in javascript. It makes some people confusion some times, like me. Here let us to make it clear.

Syntax

call([thisObj[,arg1[, arg2[, [,.argN]]]]])

• thisObj (optional): it’s object which can be act as currently this object.
• arg1, arg2, argN (optional) : the parameters which can be passed to the method.

The call method can be used to instead of another object to invoke a method. It can change the object context of a function to a new object which thisObj referenced.
