Examples of org.apache.lucene.search.TimeLimitingCollector$TimerThread

org.apache.lucene.search.TimeLimitingCollector
The {@link TimeLimitingCollector} is used to timeout search requests thattake longer than the maximum allowed search time limit. After this time is exceeded, the search thread is stopped by throwing a {@link TimeExceededException}.

    Collector maybeTimeLimitingCollector = collector;
    if ( timeoutManager.getType() == TimeoutManager.Type.LIMIT ) {
      final Long timeoutLeft = timeoutManager.getTimeoutLeftInMilliseconds();
      if ( timeoutLeft != null ) {
        Counter counter = timeoutManager.getLuceneTimeoutCounter();
        maybeTimeLimitingCollector = new TimeLimitingCollector( collector, counter, timeoutLeft);
      }
    }
