Method Detail

getMaxQueueLength

public int getMaxQueueLength()

getIndexName

public String getIndexName()

getIndexManager

public IndexManager getIndexManager()

getWorkVisitor

public IndexWorkVisitor<Void,LuceneWorkExecutor> getWorkVisitor()

getWorkspace

public AbstractWorkspaceImpl getWorkspace()

shutdown

public void shutdown()

getErrorHandler

public ErrorHandler getErrorHandler()

getParallelModificationLock

public Lock getParallelModificationLock()

getExclusiveModificationLock

public Lock getExclusiveModificationLock()

onTheFlyRebuild

public LuceneBackendResources onTheFlyRebuild()

Creates a replacement for this same LuceneBackendResources: reuses the existing locks and executors (which can't be reconfigured on the fly), reuses the same Workspace and ErrorHandler, but will use a new LuceneWorkVisitor. The LuceneWorkVisitor contains the strategies we use to apply update operations on the index, and we might need to change them after the backend is started.

Returns:

the new LuceneBackendResources to replace this one.

flushAndReleaseResources

public void flushAndReleaseResources()

submitToAsyncIndexingExecutor

public void submitToAsyncIndexingExecutor(org.hibernate.search.backend.impl.lucene.LuceneBackendQueueTask luceneBackendQueueProcessor)
