All Implemented Interfaces:

Executor.Work, ApplicationContextAware

Deprecated.

@Deprecated
public class FullTextIndexer
extends Executor.SimpleWork
implements ApplicationContextAware

Constructor Detail

FullTextIndexer

public FullTextIndexer(EventLogLoader ll)

Deprecated.

FullTextIndexer

public FullTextIndexer(EventLogLoader ll,
                       Metrics metrics)

Deprecated.

Method Detail

setRepetitions

public void setRepetitions(int reps)

Deprecated.

Spring injector. Sets the number of indexing runs will be made if there is a substantial backlog.

setReportingLoops

public void setReportingLoops(int loops)

Deprecated.

setDryRun

public void setDryRun(boolean dryRun)

Deprecated.

setApplicationContext

public void setApplicationContext(ApplicationContext ctx)

Deprecated.

Specified by:

setApplicationContext in interface ApplicationContextAware

setSqlAction

public void setSqlAction(SqlAction sql)

Deprecated.

Since these instances are used repeatedly, we need to check for already set SqlAction

Overrides:

setSqlAction in class Executor.SimpleWork

doWork

@Transactional(readOnly=false,
               isolation=SERIALIZABLE)
public Object doWork(org.hibernate.Session session,
                                                                                           ServiceFactory sf)

Deprecated.

Runs doIndexing(FullTextSession) within a Lucene transaction. doIndexing(FullTextSession) will also be called

Specified by:

doWork in interface Executor.Work

Parameters:

session - non null.

sf - non null.

Returns:

Any results which will be used by non-wrapped code.

doIndexing

public int doIndexing(org.hibernate.search.FullTextSession session)

Deprecated.

handleEventLog

protected void handleEventLog(org.hibernate.search.FullTextSession session,
                              EventLog eventLog)

Deprecated.

doMore

public boolean doMore(int count)

Deprecated.

Default implementation suggests doing more if fewer than reps runs have been made and if there are still more than EventLogLoader.batchSize x 100 backlog entries. This is based on the assumption that indexing runs roughly 120 times an hour, so if there are more than an hours worth of batches, do extra work to catch up.

asClassOrNull

protected Class asClassOrNull(String str)

Deprecated.

get

protected IObject get(org.hibernate.Session session,
                      Class type,
                      long id)

Deprecated.
