AOP and AspectJ

1st - radical extension of Java:

Need to understand philosophy - oop doesn't give us enough flexibility

1. First look at mechanics
2. Then try to understand what it really gives us (neat trick?)

 - tell them where to download, what to read

3. Mechanics in detail.

  *  aspect structure

  *  advice : before, after, around

     show proceed in around

  *  Join points and pointcuts

 	The difference.

	Call signature
	
	   call(private * *.f(..))
	   execution(A.new(..))
	   get and set
	   within and withincode
  	   && || !
	   args
	   this and target

	pointcut defintions

  *  inter-type declarations.
