Method Detail

initialize

public void initialize(Properties props,
                       WorkerBuildContext context,
                       DirectoryBasedIndexManager indexManager)

Description copied from interface: BackendQueueProcessor

Used at startup, called once as first method.

Specified by:

initialize in interface BackendQueueProcessor

Overrides:

initialize in class JGroupsBackendQueueProcessor

Parameters:

props - all configuration properties

context - context giving access to required meta data

indexManager - the index it is related to.

getMasterListener

public org.jgroups.Receiver getMasterListener()

close

public void close()

Description copied from interface: BackendQueueProcessor

Used to shutdown and eventually release resources. No other method should be used after this one.

Specified by:

close in interface BackendQueueProcessor

Overrides:

close in class JGroupsBackendQueueProcessor

applyWork

public void applyWork(List<LuceneWork> workList,
                      IndexingMonitor monitor)

Description copied from interface: BackendQueueProcessor

Applies a list of operations to the index. A single list might be processed by applying elements in parallel threads, but no work should be started on a new workList until the previous one was fully processed. Work could be applied asynchronously according to capabilities and configuration of implementor. A null parameter is not acceptable, implementations should throw an IllegalArgumentException.

Parameters:

workList - list of Lucene work instance which need to be applied to the index

applyStreamWork

public void applyStreamWork(LuceneWork singleOperation,
                            IndexingMonitor monitor)

Description copied from interface: BackendQueueProcessor

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)

Parameters:

singleOperation - single Lucene work instance to be applied to the index

getExclusiveWriteLock

public Lock getExclusiveWriteLock()

Returns:

a Lock instance which will block index modifications when acquired
