Question

Lets say that i have 3 entities, a, b and c. Connected as a <- b <- c.

I make 2 instances of a; a1 and a2. Both of them have some b:s and c:s connected to them.

What i would like to do is to replace a1 wuth a2, including their children. In other words; removing a1 and its children, adding a2 + childrens on the same ID. Hope you get the idea, otherwise ill elaborate.

Thanks in advance

Answer 1

var tempB = a1.b;
var tempC = a1.c;

a1.b = a2.b;
a1.c = a2.c;

a2.b = tempB;
a2.c = tempC;

Or, perhaps:

var tempID = a1.ID;
a1.ID = a2.ID;
a2.ID = tempID;

I may have messed up with hierarchy; so:

var tempB = a1.b;

a1.b = a2.b;
a2.b = tempB;

// this copies c instances together with b instances
