IBM ILOG OPL JavaScript Reference: Class IloIntervalSequenceVar

Class IloIntervalSequenceVar

IloIntervalSequenceVar

Description:: Iterating Properties: Default behavior.

Example:

using CP;

range R = 1..3;

dvar interval tia[i in R] size i;
dvar sequence seq in tia;

subject to {
  noOverlap(seq);

  before(seq, tia[2], tia[3]);
  prev(seq, tia[1], tia[3]);
}

execute {
  writeln(seq);
  writeln(seq.first() );
  writeln(seq.next(seq.first() ) );
  writeln(seq.last() );

  writeln("loop");
  var s=seq.first();
  for(var i in R)
  {
   writeln(s);
   s=seq.next(s) ;
  }
  writeln(s);
}

After execution the Scripting log shows:

<1 0 2 2>
<1 2 3 1>
<1 3 6 3>
loop
<1 0 2 2>
<1 2 3 1>
<1 3 6 3>
null
