.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
The \f(CW\*(C`after\*(C'\fR advice type is used to execute code after a function is called,
regardless of whether or not the function returned normally or threw an 
exception.
.PP
The \f(CW\*(C`after\*(C'\fR advice type should be used when you need to potentially make
multiple different changes to the returned value or the thrown exception.
.PP
If you only care about normally returned values you should use \f(CW\*(C`returning\*(C'\fR in
the pointcut to exclude join points occuring due to exceptions.
.PP
If you only care about handling exceptions you should use \f(CW\*(C`throwing\*(C'\fR in the
pointcut to exclude join points occuring due to normal return.
