java.lang.Objectorg.hibernate.search.backend.impl.lucene.LuceneBackendQueueProcessor
public class LuceneBackendQueueProcessor
This will actually contain the Workspace and LuceneWork visitor implementation, reused per-DirectoryProvider. Both Workspace(s) and LuceneWorkVisitor(s) lifecycle are linked to the backend lifecycle (reused and shared by all transactions). The LuceneWorkVisitor(s) are stateless, the Workspace(s) are threadsafe.

void |
applyStreamWork(LuceneWork singleOperation,
IndexingMonitor monitor)
Applies a single operation on the index, and different operations can be applied in parallel, even in parallel to a workList instance being processed by BackendQueueProcessor.applyWork(List, IndexingMonitor) |
void |
applyWork(List<LuceneWork> workList,
IndexingMonitor monitor)
Applies a list of operations to the index. |
void |
close()
Used to shutdown and eventually release resources. |
Lock |
getExclusiveWriteLock()
|
LuceneBackendResources |
getIndexResources()
|
void |
indexMappingChanged()
Used to notify the backend that the number or type of indexed entities being indexed in this backend changed. |
void |
initialize(Properties props,
WorkerBuildContext context,
DirectoryBasedIndexManager indexManager)
Used at startup, called once as first method. |
void |
setCustomWorkspace(AbstractWorkspaceImpl workspace)
If invoked before initialize(Properties, WorkerBuildContext, DirectoryBasedIndexManager)
it can set a customized Workspace instance to be used by this backend. |
