Constructor Detail

DirectoryBasedIndexManager

public DirectoryBasedIndexManager()

Method Detail

getIndexName

public String getIndexName()

Description copied from interface: IndexManager

Useful for labeling and logging resources from this instance.

Specified by:

getIndexName in interface IndexManager

Returns:

the name of the index maintained by this manager.

getReaderProvider

public ReaderProvider getReaderProvider()

Description copied from interface: IndexManager

Provide access to IndexReaders.

Specified by:

getReaderProvider in interface IndexManager

Returns:

a ReaderProvider instance for the index managed by this instance

destroy

public void destroy()

Description copied from interface: IndexManager

Called when a SearchFactory is stopped. This method typically releases resources.

Specified by:

destroy in interface IndexManager

initialize

public void initialize(String indexName,
                       Properties properties,
                       org.apache.lucene.search.Similarity similarity,
                       WorkerBuildContext buildContext)

Description copied from interface: IndexManager

Initialize this IndexManager before its use.

Specified by:

initialize in interface IndexManager

Parameters:

indexName - the unique name of the index (manager). Can be used to retrieve a IndexManager instance via the search factory and IndexManagerHolder.

properties - the configuration properties

buildContext - context information needed to initialize this index manager

getContainedTypes

public Set<Class<?>> getContainedTypes()

Specified by:

getContainedTypes in interface IndexManager

Returns:

the set of classes being indexed in this manager

getSimilarity

public org.apache.lucene.search.Similarity getSimilarity()

Specified by:

getSimilarity in interface IndexManager

Returns:

the Similarity applied to this index. Note, only a single Similarity can be applied to a given index.

performStreamOperation

public void performStreamOperation(LuceneWork singleOperation,
                                   IndexingMonitor monitor,
                                   boolean forceAsync)

Description copied from interface: IndexManager

Perform a single non-transactional operation, best to stream large amounts of operations. Operations might be applied out-of-order! To mark two series of operations which need to be applied in order, use a transactional operation between them: a transactional operation will always flush all streaming operations first, and be applied before subsequent streaming operations.

Specified by:

performStreamOperation in interface IndexManager

Parameters:

singleOperation - the operation to perform

monitor - no be notified of indexing events

forceAsync - if true, the invocation will not block to wait for it being applied. When false this will depend on the backend configuration.

performOperations

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

Description copied from interface: IndexManager

Used to apply update operations to the index. Operations can be applied in sync or async, depending on the IndexManager implementation and configuration.

Specified by:

performOperations in interface IndexManager

Parameters:

workList - the list of write operations to apply.

monitor - no be notified of indexing events

toString

public String toString()

Overrides:

toString in class Object

getAnalyzer

public org.apache.lucene.analysis.Analyzer getAnalyzer(String name)

Specified by:

getAnalyzer in interface IndexManager

Parameters:

name - the name of the analyzer to retrieve.

Returns:

Returns the Analyzer with the given name (see also AnalyzerDef)

setSearchFactory

public void setSearchFactory(SearchFactoryImplementor boundSearchFactory)

Description copied from interface: IndexManager

Connects this IndexManager to a new SearchFactory.

Specified by:

setSearchFactory in interface IndexManager

Parameters:

boundSearchFactory - the existing search factory to which to associate this index manager with

addContainedEntity

public void addContainedEntity(Class<?> entity)

Specified by:

addContainedEntity in interface IndexManager

Parameters:

entity - Adds the specified entity type to this index manager, making it responsible for manging this type.

optimize

public void optimize()

Description copied from interface: IndexManager

To optimize the underlying index. Some implementations might ignore the request, if it doesn't apply to them.

Specified by:

optimize in interface IndexManager

getSerializer

public LuceneWorkSerializer getSerializer()

Specified by:

getSerializer in interface IndexManager

Returns:

the Serializer implementation used for this IndexManager
