-!!! Read/Write Lock Aspect 
-available within our CVS 
- 
-!!Goal 
-This Aspect is an example of an implementation of the Read/Write Lock pattern. 
-It allows u to define at the method level a read/write lock using 
-either annotation or an XML file 
- 
-The implementation is based on the concurrent package from Doug Lea. 
- 
-!!Problem 
- 
-!Let's see a simple example defining the problem to solve. 
-{{{
-public class Account
-{
-private float balance; 
-
-public Account(float balance) 
-{ 
- this.balance=balance; 
-} 
-
-public void debit(float amount) 
-{ 
-// Implementation to debit the account balance 
- ... 
-} 
-
-public void credit(float amount) 
-{ 
-// Implementation to credit the account balance 
-... 
-} 
-
-public String toString() 
-{ 
-// Implementation to format the account description 
-... 
-} 
-}  
-}}} 
- 
-The above class required to support concurrency invocation of the method debit,credit 
-and toString method. 
-
-!!Traditional Implementation.
-The traditional solution without AOP would be to implement the same code within the debit 
-and credit account to acquire/release a write lock.A read lock would be required for the toString method. 
- 
-!!Solution with Read/Write Lock Aspect 
- 
-The concurrency code is refactored within the Read/Write Lock Aspect.So the new Aspect can be applied 
-against any method using annotation or an XML file. 
- 
-!Here the new code of the Account class with annotation
