Methods in org.apache.lucene.index with parameters of type InfoStream

Modifier and Type	Method	Description
(package private) static void	IndexWriter.createCompoundFile(InfoStream infoStream, TrackingDirectoryWrapper directory, SegmentInfo info, IOContext context, IOUtils.IOConsumer<Collection<String>> deleteFiles)	NOTE: this method creates a compound file for all files returned by info.files().

(package private) static void	IndexFileDeleter.inflateGens(SegmentInfos infos, Collection<String> files, InfoStream infoStream)	Set all gens beyond what we currently see in the directory, to avoid double-write in cases where the previous IndexWriter did not gracefully close/rollback (e.g.
(package private) void	ConcurrentMergeScheduler.initialize(InfoStream infoStream, Directory directory)
(package private) void	MergeScheduler.initialize(InfoStream infoStream, Directory directory)	IndexWriter calls this on init.
IndexWriterConfig	IndexWriterConfig.setInfoStream(InfoStream infoStream)	Information about merges, deletes and a message when maxFieldLength is reached will be printed to this.
boolean	ReadersAndUpdates.writeFieldUpdates(Directory dir, FieldInfos.FieldNumbers fieldNumbers, long maxDelGen, InfoStream infoStream)
