示例1: comparatorFieldComparator
import org.apache.lucene.search.SortField; //导入方法依赖的package包/类
Comparator<ShardDoc> comparatorFieldComparator(SortField sortField) {
final FieldComparator fieldComparator;
try {
fieldComparator = sortField.getComparator(0, 0);
} catch (IOException e) {
throw new RuntimeException("Unable to get FieldComparator for sortField " + sortField);
}
return new ShardComparator(sortField) {
// Since the PriorityQueue keeps the biggest elements by default,
// we need to reverse the field compare ordering so that the
// smallest elements are kept instead of the largest... hence
// the negative sign.
@Override
public int compare(final ShardDoc o1, final ShardDoc o2) {
//noinspection unchecked
return -fieldComparator.compareValues(sortVal(o1), sortVal(o2));
}
};
}
示例2: GroupComparator
import org.apache.lucene.search.SortField; //导入方法依赖的package包/类

for (int compIDX = 0; compIDX < sortFields.length; compIDX++) {
final SortField sortField = sortFields[compIDX];
comparators[compIDX] = sortField.getComparator(1, compIDX);
reversed[compIDX] = sortField.getReverse() ? -1 : 1;
}
