Method Detail

numberOfShards

public int numberOfShards()

getIndexEventListener

public IndexEventListener getIndexEventListener()

iterator

public java.util.Iterator<IndexShard> iterator()

Specified by:

iterator in interface java.lang.Iterable<IndexShard>

hasShard

public boolean hasShard(int shardId)

getShardOrNull

@Nullable
public IndexShard getShardOrNull(int shardId)

Return the shard with the provided id, or null if there is no such shard.

Specified by:

getShardOrNull in interface IndicesClusterStateService.AllocatedIndex<IndexShard>

getShard

public IndexShard getShard(int shardId)

Return the shard with the provided id, or throw an exception if it doesn't exist.

shardIds

public java.util.Set<java.lang.Integer> shardIds()

cache

public IndexCache cache()

fieldData

public IndexFieldDataService fieldData()

getIndexAnalyzers

public IndexAnalyzers getIndexAnalyzers()

mapperService

public MapperService mapperService()

xContentRegistry

public NamedXContentRegistry xContentRegistry()

similarityService

public SimilarityService similarityService()

close

public void close(java.lang.String reason,
                  boolean delete)
           throws java.io.IOException

Throws:

java.io.IOException

indexUUID

public java.lang.String indexUUID()

createShard

public IndexShard createShard(ShardRouting routing)
                       throws java.io.IOException

Throws:

java.io.IOException

removeShard

public void removeShard(int shardId,
                        java.lang.String reason)

Description copied from interface: IndicesClusterStateService.AllocatedIndex

Removes shard with given id.

Specified by:

removeShard in interface IndicesClusterStateService.AllocatedIndex<IndexShard>

getIndexSettings

public IndexSettings getIndexSettings()

Description copied from interface: IndicesClusterStateService.AllocatedIndex

Returns the index settings of this index.

Specified by:

getIndexSettings in interface IndicesClusterStateService.AllocatedIndex<IndexShard>

Overrides:

getIndexSettings in class AbstractIndexComponent

newQueryShardContext

public QueryShardContext newQueryShardContext(int shardId,
                                              org.apache.lucene.index.IndexReader indexReader,
                                              java.util.function.LongSupplier nowInMillis)

Creates a new QueryShardContext. The context has not types set yet, if types are required set them via QueryShardContext.setTypes(String...). Passing a null IndexReader will return a valid context, however it won't be able to make IndexReader-specific optimizations, such as rewriting containing range queries.

getThreadPool

public ThreadPool getThreadPool()

The ThreadPool to use for this index.

getBigArrays

public BigArrays getBigArrays()

The BigArrays to use for this index.

getScriptService

public ScriptService getScriptService()

The ScriptService to use for this index.

updateMapping

public boolean updateMapping(IndexMetaData indexMetaData)
                      throws java.io.IOException

Description copied from interface: IndicesClusterStateService.AllocatedIndex

Checks if index requires refresh from master.

Specified by:

updateMapping in interface IndicesClusterStateService.AllocatedIndex<IndexShard>

Throws:

java.io.IOException

getMetaData

public IndexMetaData getMetaData()

updateMetaData

public void updateMetaData(IndexMetaData metadata)

Description copied from interface: IndicesClusterStateService.AllocatedIndex

Updates the meta data of this index. Changes become visible through IndicesClusterStateService.AllocatedIndex.getIndexSettings()

Specified by:

updateMetaData in interface IndicesClusterStateService.AllocatedIndex<IndexShard>
