Eager Replication (3)

Original roles for i, gi

( i is active, gi is passive)

AA.set(i,10){

AA.i=10;

//BB.gi=10;

AB__BB->gi = 10;

} // before role-swapping

Role reversal for s, gs:

// gs is active, s is passive)

BB.set(gs,”ten”){

strcpy(gs, ”ten”);

strcpy(AA.s, AAcurr-> AA__BB->gs);

} // s and gs swap roles

AA

AAid AA0..0 c8 1 //..

x x 0 int 0 //..

s x “?” c20 0 //..

BB

BBid BB0..0 c8 1 //..

gx 0 int //...

gs “?” c20 //

AB

#define AA__BB

ABid_fcp -> Bbid_pp

(Using instance navigation paths of CHGEN:

AB is 1:1 optional association between AA and BB)

#define BB__AA

ABid_fcp ->AAid_pp
