示例1: PagingFieldCollector

import org.apache.lucene.search.FieldValueHitQueue.Entry; //导入依赖的package包/类
public PagingFieldCollector(
                            FieldValueHitQueue<Entry> queue, FieldDoc after, int numHits, boolean fillFields,
                            boolean trackDocScores, boolean trackMaxScore) {
  super(queue, numHits, fillFields);
  this.queue = queue;
  this.trackDocScores = trackDocScores;
  this.trackMaxScore = trackMaxScore;
  this.after = after;
  comparators = queue.getComparators();
  reverseMul = queue.getReverseMul();

  // Must set maxScore to NEG_INF, or otherwise Math.max always returns NaN.
  maxScore = Float.NEGATIVE_INFINITY;

  // Tell all comparators their top value:
  for(int i=0;i<comparators.length;i++) {
    @SuppressWarnings("unchecked")
    FieldComparator<Object> comparator = (FieldComparator<Object>) comparators[i];
    comparator.setTopValue(after.fields[i]);

  // fillFields to true.
