If you want the definition of the pointcut then it is a similar the code element which can able to collect the join points and bring data data from the execution context of that join points. Most of the time use of the Pointcut is done with the advice. It provide the facility to create a boolean operators to build up other pointcuts. So, it help to create other pointcuts also.

While declaring Pointcuts you need to make use of the code below:

@Pointcut("call(* *.*(..))")
void Method() 
{
}

Or you can simply use the

pointcut Method() : call(* *.*(..));

Pointcuts provides you following methods:

• equals(Pointcut one, Pointcut two)
• intersection(Pointcut one, Pointcut two)
• matches(Pointcut one, Method met, Class target, Object[] args)
• union(Pointcut one, Pointcut two)

Class Pointcuts comes under the java.lang.Object which is extended by org.springframework.aop.support.Pointcuts. This class provides the constants which are having ability to match the getters and setters. It also provides you the facility of the static methods which are useful for performing and evaluating pointcuts. You can make use of these methods for creating the Pointcuts with the help of the union and intersection methods.
