It syncronizes the local search index segments with the database, by sipping each segment and pushing it to the database. Each Segment has an extra file that contains an MD5 of the segment and a time stamp of the last update. If any segments are missing in the local segment store (including no segments at all, as with a new cluster node) the missing segments are downloaded from the JDBC store. If any of the segments on the local store are found to be dammaged they are reloaded from the database. author:    ieb Method Summary public  boolean centralIndexExists()      public  void dolog(String message)      public  DataSource getDataSource()      public  long getLastUpdate()      public  List<SegmentInfo> getLocalSegments()      public  List<SegmentInfo> getLocalSegments(File searchDir, List<SegmentInfo> l)      public  void getLock()      public  SearchService getSearchService()      public  List getSegmentInfoList()      public  long getSegmentInfoList(File searchDir, List seginfo)      public  String getSegmentName(String segmentPath)      public  String getSharedSegments()      public  File getTemporarySegment(boolean delete)      public  void init()      public  boolean isLocalSegmentsOnly()      public  boolean isLocalStructuredStorage()      public  boolean isMultipleIndexers()      public  boolean isParallelIndex()      public  boolean isSharedStructuredStorage()      public  boolean isValidate()      public  SegmentInfo newSegment()      public  void recoverSegment(SegmentInfo recoverSegInfo)      public  void releaseLock()      public  void removeLocalSegment(SegmentInfo rmsi)      public  void removeTemporarySegment()      public  List<SegmentInfo> saveAllSegments()      public  List<SegmentInfo> saveSegments()      public  SegmentInfo saveTemporarySegment()      public  void setAutoDdl(boolean autoDdl)      public  void setDataSource(DataSource dataSource)      public  void setLocalSegmentsOnly(boolean localSegmentsOnly)      public  void setLocalStructuredStorage(boolean localStructuredStorage)      public  void setLocation(String location)      public  void setParallelIndex(boolean parallelIndex)      public  void setSearchService(SearchService searchService)      public  void setSharedSegments(String sharedSegments)      public  void setSharedStructuredStorage(boolean sharedStructuredStorage)      public  void setValidate(boolean validate)      protected  void updateDBPatch(Connection connection)      protected  void updateDBPatchBLOB(Connection connection)      protected  void updateDBPatchFilesystem(Connection connection)      protected  void updateDBSegment(Connection connection, SegmentInfo addsi)      protected  void updateDBSegmentBLOB(Connection connection, SegmentInfo addsi)      protected  void updateDBSegmentFilesystem(Connection connection, SegmentInfo addsi)      protected  void updateLocalPatch(Connection connection)      protected  void updateLocalPatchFilesystem(Connection connection)      protected  void updateLocalSegment(Connection connection, SegmentInfo addsi)      protected  void updateLocalSegmentBLOB(Connection connection, SegmentInfo addsi)      protected  void updateLocalSegmentFilesystem(Connection connection, SegmentInfo addsi)      public  List<SegmentInfo> updateSegments()      Method Detail centralIndexExists public boolean centralIndexExists()(Code) dolog public void dolog(String message)(Code) getDataSource public DataSource getDataSource()(Code) Returns the dataSource. getLastUpdate public long getLastUpdate()(Code) getLocalSegments public List<SegmentInfo> getLocalSegments() throws IOException(Code) get a list of local segments throws:   IOException -
