--------------------------------------
Summary: make sentinel object in HitQueue a singleton?
Key: LUCENE-4368
URL: https://issues.apache.org/jira/browse/LUCENE-4368
Project: Lucene - Core
Issue Type: Improvement
Components: core/search
Affects Versions: 4.0-BETA
Reporter: Steven Bethard
Via jvisualvm, I see that one of my Lucene processes is spending a lot of time
in HitQueue.getSentinelObject. That's a very simple method that currently looks
like:
protected ScoreDoc getSentinelObject() {
return new ScoreDoc(Integer.MAX_VALUE, Float.NEGATIVE_INFINITY);
}
Since the same sentinel is always returned, perhaps the sentinel should be
declared as a static variable on HitQueue and then getSentinelObject() would
just return that static value?
