Can I use tuple key to find a tuple in a tupleset iusing OPLScript? The following line didn't work for me:

OPDModel1.ctDeverseMax[OPDData.relOEs.find(ctn.esp)

Where

ctn.esp

is an

int

and

relOEs

is:

tuple rvOE 
{   key 

int espOE;   string nomOE;   

int espReservoirAmont;   

int espSegmentAval;   

int NonControlable;   
}   
{rvOE
} relOEs = ...;

I receive the following error message: Scripting runtime error: not of type 'IloTuple', "246".
For your information, ctn.esp=246.

Hi,

instead of find you should use Opl.item

with item you can use the rank or the key

If I write

Opl.item(OPDData.relOEs,ctn.esp)

, the function interpret that

ctn.esp

is an index and not a tuple key. How can I do to tell the compiler that

ctn.esp

is an index?

Thank you,

Hi Blais,

Try
item(OPDData.relOEs,ctn.esp)
but I think sets do not have to preserve order, keep that in mind.
There are sorted sets, like
sorted {rvOE} relOEs = ...;
but not sure how it works with tuples, I use sorted sets with ints.

Another approach is to replace the set with an array
int N = card(OPDData.relOEs);
rvOE_Array http://i in 1..N = item(OPDData.relOEs, i);

The function

OPDData.relOEs.find(ctn.esp)

work well. The error I have come from another part of my code.

Sorry,
