Re: [ajdt-dev] Declaring methods in interface through Aspect

[vinodh.t.subbiah@xxxxxxxxxxxx]

Hi All,
I checked the compiled classes(open it with
cavaj) found the interface is created with out any implementation.The sytem.out
line was also not there but it stayed in aspect(compiled file) as a static
method with the System.out. Implementation.So is that means I cant declare
in a interface ?Or do i make it to be abstract.
Thanks,

Hi All, 
 Im trying to add a method declaration in an Interface IAccountSDB.
But when i try to add it in Aspect it gives me compilation error saying
no body implemented.Then I try to implement the body in the Class SDBRental
which extends the IAccountSDB. 
Still I was getting the error and finally i add the dummy implementation
{ ...} and it got compiled and also running correctly.But why i need to
provide this implementation when I want to really declare the method in
interface only? 
Code shown as below. 

Also it is not giving any compilation error if the sub class does not implement
the methods in interface !.When i run i saw the method declared in interface
gets called !Please help to resolve this issue.(It behaves like abstract
class implementation)
