RE: [aspectj-users] Why this implementation ?

["Louth, William" <william.louth@xxxxxx>]

Hi Michael,

I would assume its because the method parameters are not final and an
assignment could be made during the method's execution which would
invalidate a reference. Otherwise the compiler would have to do further
analysis of the methods bytecodes to determine which parameters are
reused (reference modified).

William

Subject: [aspectj-users] Why this implementation ?


Hi,

I'm using an around advice and decompiled the code. Then I get the 
following:

    public String createCustomer(String s, String s1, String s2, String 
s3, String s4, String s5, String s6,
            String s7, String s8) throws InvalidParameterException {
        String s9 = s;
        String s10 = s1;
        String s11 = s2;
        String s12 = s3;
        String s13 = s4;
        String s14 = s5;
        String s15 = s6;
        String s16 = s7;
        String s17 = s8;
        BasicDukeEJBTimeAspect.ajc$perObjectBind(this);
        if (BasicDukeEJBTimeAspect.hasAspect(this)) {
            return (String)createCustomer_aroundBody3$advice(this, s9, 
s10, s11, s12, s13, s14, s15, s16, s17, 
BasicDukeEJBTimeAspect.aspectOf(this), null, ajc$tjp_1);
        } else {
            return createCustomer_aroundBody2(this, s9, s10, s11, s12, 
s13, s14, s15, s16, s17);
        }
    }

Does anybody know why s10 - s17 are used here? I think its just
overhead.

Thanks,
Michael Dempfle
