示例1: intersection
import org.apache.lucene.util.FixedBitSet; //导入方法依赖的package包/类
@Override
public DocSet intersection(DocSet other) {
// intersection is overloaded in the smaller DocSets to be more
// efficient, so dispatch off of it instead.
if (!(other instanceof BitDocSet)) {
return other.intersection(this);
}
// Default... handle with bitsets.
FixedBitSet newbits = getBits().clone();
newbits.and(toBitSet(other));
return new BitDocSet(newbits);
}
