Dear all,
May i ask please about usage a bit here?
Previously I had:
import com.carrotsearch.hppc.IntSet;
import com.carrotsearch.hppc.IntOpenHashSet;
IntSet columnValues = new IntOpenHashSet();
for loop (...) {
if (columnValues.contains(x)) continue;
...
columnValues.add(x);
}
It worked well. Now I changed:
import org.apache.mahout.math.set.AbstractIntSet;
import org.apache.mahout.math.set.OpenIntHashSet;
AbstractIntSet columnValues = new OpenIntHashSet();
for loop (...) {
if (columnValues.contains(x)) continue;
...
columnValues.add(x);
}
And it works for up to 5 added elements and then hangs on forever. I'm
sorry, how correctly should I use a simple integer hashset here? I guess
something wrong in initialization step. Unfortunately in javadoc there is
no explanation on how to use your classes so I'm asking here.
Thank you and have a nice day!
