hello...
i have the following definition of the upleMap MybusCategoryIdx:

ILOG.Concert.ITupleMap MybusCategoryIdx=oplCP.GetElement("busCategoryIdx").AsTupleMap();

how i can get one tuple of this TupleMap ??



thank you

Hi,

To get a tuple from the tuple map you could do:


tuple T {
int a;
int b;
};

T toto[ i in 1..3 ][ j in 10..13 ] = <i, j*2>;



    ITupleMap tupleMap = opl.GetElement( "toto" ).AsTupleMap();

    IMapIndexArray indexArray = oplF.MapIndexArray( 0 );
    indexArray.Add( 1 );
    indexArray.Add( 12 );

    // Before calling ITuple.GetAt(...), you must use ITuple.MakeTuple()
    // to create an empty tuple
    ITuple tuple = tupleMap.MakeTuple();
    tupleMap.GetAt( indexArray, tuple );

Hi,

let me give you a C++ example:

if you have in your .mod

tuple t
{
int a;
int b;
}

{string} r={"Monday","Tuesday"};
t s[r]=[<1,2>,<2,3>];

then to read the s for Tuesday you could write

IloTupleMap s= opl.getElement("s").asTupleMap();
IloMapIndexArray ids(env, 0);
ids.add("Tuesday");
IloTuple res = s.makeTuple();
s.getAt(ids, res);
cout << res << endl;<br />
which gives

<2,3>

Hope this helps
