Syntax
'Declaration
Public NotInheritable Class SetBuilder _
Implements IDisposable

end
public final class SetBuilder implements IDisposable
Examples
The following example takes a set and a return count, and randomly retrieves tuples from the set, returning a final subset.
public Set RandomSample(Set set, int returnCount)
{
//Return the original set if there are fewer tuples
//in the set than the number requested.
if (set.Tuples.Count <= returnCount)
return set;
System.Random r = new System.Random();
SetBuilder returnSet = new SetBuilder();
//Retrieve random tuples until the return set is filled.
int i = set.Tuples.Count;
foreach (Tuple t in set.Tuples)
{
if (r.Next(i) < returnCount)
{
returnCount--;
returnSet.Add(t);
}
i--;
//Stop the loop if we have enough tuples.
if (returnCount == 0)
break;
}
return returnSet.ToSet();
}
