示例1: reduceOpenFiles
import org.apache.lucene.index.MergeScheduler; //导入依赖的package包/类
/** just tries to configure things to keep the open file
* count lowish */
public static void reduceOpenFiles(IndexWriter w) {
// keep number of open files lowish
MergePolicy mp = w.getConfig().getMergePolicy();
if (mp instanceof LogMergePolicy) {
LogMergePolicy lmp = (LogMergePolicy) mp;

if (ms instanceof ConcurrentMergeScheduler) {
// wtf... shouldnt it be even lower since its 1 by default?!?!
((ConcurrentMergeScheduler) ms).setMaxMergesAndThreads(3, 2);
}
}
示例2: reduceOpenFiles
import org.apache.lucene.index.MergeScheduler; //导入依赖的package包/类

示例4: clone

@Override
public MergeScheduler clone() {
// Lucene IW makes a clone internally but since we hold on to this instance
// the clone will just be the identity.
