This is a Java app, using a model developed in OPL, running CPLEX.

IloTupleSet mySet = opl.getElement("mySet").asTupleSet();
for (Iterator it1 = mySet.iterator(); it1.hasNext();){
    IloTuple oneofMySet = (IloTuple) it1.next();

Now given that the definition of oneofMySet would read as follows (in OPL)
tuple oneofMySet{
tuple_i_defined t1;
tuple_i_defined_also t2;
int someNumber;
}

How do I extract t1 and t2 so that I can do something useful with them?

TIA, Alan

Hi,

you  might look at :

IloTuple makeTupleValue(java.lang.String col)
          Creates and returns the IloTuple value of the given column of the invoking tuple.

with col = "t1"

Here's the online help for that function

[b]makeTupleValue[/b]
IloTuple makeTupleValue(java.lang.String col)


Not exactly verbose, is it?
If it had said "getTupleValue" I'd have tried it, just as I tried a dozen other functions.
"make" implies construction, not retrieval (at least to me).

With that said, it does exactly what I need it to.
I appreciate the help.
Alan

Hi,

it is "make", as the structure returned (IloTuple) needs to be created.
"get" is used for basic type where no such structure is created.
