Creates a new instance with
CopyC#
size
 elements. If
CopyC#
prePopulate
 is set to true, the queue will pre-populate itself with sentinel objects and set its {@link #Size()} to
CopyC#
size
. In that case, you should not rely on {@link #Size()} to get the number of actual elements that were added to the queue, but keep track yourself.
NOTE: in case
CopyC#
prePopulate
 is true, you should pop elements from the queue using the following code example: 
            PriorityQueue pq = new HitQueue(10, true); // pre-populate.
            ScoreDoc top = pq.top();
            
            // Add/Update one element.
            top.score = 1.0f;
            top.doc = 0;
            top = (ScoreDoc) pq.updateTop();
            int totalHits = 1;
            
            // Now pop only the elements that were *truly* inserted.
            // First, pop all the sentinel elements (there are pq.size() - totalHits).
            for (int i = pq.size() - totalHits; i > 0; i--) pq.pop();
            
            // Now pop the truly added elements.
            ScoreDoc[] results = new ScoreDoc[totalHits];
            for (int i = totalHits - 1; i >= 0; i--) {
            results[i] = (ScoreDoc) pq.pop();
            }
