Examples of java.util.BitSet.clone()

java.util.BitSet.clone()
Cloning this BitSet produces a new BitSet that is equal to it. The clone of the bit set is another bit set that has exactly the same bits set to true as this bit set.
Overrides the clone method of Object. @return a clone of this bit set. @see java.util.BitSet#size()

    //SHOULD filters
    if (shouldFilters!=null)
    {
      returnBits = ((Filter)shouldFilters.get(0)).bits(reader);
//      avoid changing the original bitset - it may be cached
      returnBits=(BitSet) returnBits.clone(); 
      if (shouldFilters.size() > 1)
      {
        for (int i = 1; i < shouldFilters.size(); i++)
        {
          returnBits.or(((Filter)shouldFilters.get(i)).bits(reader));
