Class Slf4JInfoStream

java.lang.Object
  org.apache.lucene.util.InfoStream
      com.atlassian.confluence.search.v2.lucene.Slf4JInfoStream

All Implemented Interfaces:

Closeable, Cloneable, org.springframework.beans.factory.DisposableBean, org.springframework.beans.factory.InitializingBean

public class Slf4JInfoStream
extends org.apache.lucene.util.InfoStream
implements org.springframework.beans.factory.InitializingBean, org.springframework.beans.factory.DisposableBean

Adapts Lucene's logging mechanism, InfoStream, to SLF4J.

In InfoStream, messages are categorised by "components". Generally a component is the class name or an acronym of it, e.g. the component of org.apache.lucene.index.IndexUpgrader is IndexUpgrader and the component of org.apache.lucene.index.DocumentsWriter is DW. Since there's no concept of log levels, all messages are logged under debug.

A Spring-managed instance will replace the default InfoStream within its lifecycle, thus it only makes sense to have a singleton registered.
