Defining AOP Terminology
Types Of Advice
- Before advice: The Before Advice executes before a join point. They can not prevent execution flow proceeding to the join point unless they throw an exception.
- After returning advice: After Returning Advice will be executed after a join point completes normally. If it throws exception then this type of advice will not be executed.
- After throwing advice: After Throwing Advice will be executed if a method exits by throwing an exception.
- After (finally) advice: After Advice shall be executed regardless of the means by which a join point exits normally or with exception.
- Around advice: Around Advice is the most powerful kind of advice. Around advice can perform custom behavior before and after the method invocation. It has a capability to choose whether to proceed to the join point or to shortcut the advised method execution by returning its own return value or throwing an exception.
