MergeScheduler (The Adobe AEM Quickstart and Web Application. 6.6.0)

java.lang.Object
- org.apache.lucene.index.MergeScheduler

All Implemented Interfaces:

java.io.Closeable, java.lang.AutoCloseable, java.lang.Cloneable

Direct Known Subclasses:

ConcurrentMergeScheduler, NoMergeScheduler, SerialMergeScheduler
```
public abstract class MergeScheduler
extends java.lang.Object
implements java.io.Closeable, java.lang.Cloneable
```
Expert: IndexWriter uses an instance implementing this interface to execute the merges selected by a MergePolicy. The default MergeScheduler is ConcurrentMergeScheduler.

Implementers of sub-classes should make sure that clone() returns an independent instance able to work with any IndexWriter instance.
