Method Details

numberOfShards

public int numberOfShards()

getIndexEventListener

public IndexEventListener getIndexEventListener()

iterator

public <IndexShard> iterator()

Specified by:

in interface <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 <> shardIds()

cache

public IndexCache cache()

getIndexAnalyzers

public IndexAnalyzers getIndexAnalyzers()

mapperService

public MapperService mapperService()

xContentRegistry

public org.elasticsearch.common.xcontent.NamedXContentRegistry xContentRegistry()

similarityService

public SimilarityService similarityService()

getIndexSortSupplier

public <org.apache.lucene.search.Sort> getIndexSortSupplier()

close

public void close( reason,
 boolean delete)
           throws 

Throws:

writeDanglingIndicesInfo

public void writeDanglingIndicesInfo()

deleteDanglingIndicesInfo

public void deleteDanglingIndicesInfo()

indexUUID

public  indexUUID()

createShard

public IndexShard createShard(ShardRouting routing,
 <ShardId> globalCheckpointSyncer,
 RetentionLeaseSyncer retentionLeaseSyncer)
                       throws 

Throws:

removeShard

public void removeShard(int shardId,
  reason)

Description copied from interface: IndicesClusterStateService.AllocatedIndex

Removes shard with given id.

Specified by:

removeShard in interface IndicesClusterStateService.AllocatedIndex<IndexShard>

createRecoveryState

public RecoveryState createRecoveryState(ShardRouting shardRouting,
 DiscoveryNode targetNode,
 DiscoveryNode sourceNode)

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

newSearchExecutionContext

public SearchExecutionContext newSearchExecutionContext(int shardId,
 int shardRequestIndex,
 org.apache.lucene.search.IndexSearcher searcher,
  nowInMillis,
  clusterAlias,
 <,> runtimeMappings)

Creates a new QueryShardContext. The context has not types set yet, if types are required set them via SearchExecutionContext. Passing a null IndexSearcher 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 void updateMapping(IndexMetadata currentIndexMetadata,
 IndexMetadata newIndexMetadata)
                   throws 

Description copied from interface: IndicesClusterStateService.AllocatedIndex

Updates the mappings by applying the incoming ones

Specified by:

updateMapping in interface IndicesClusterStateService.AllocatedIndex<IndexShard>

Throws:

getMetadata

public IndexMetadata getMetadata()

addMetadataListener

public void addMetadataListener(<IndexMetadata> listener)

updateMetadata

public void updateMetadata(IndexMetadata currentIndexMetadata,
 IndexMetadata newIndexMetadata)

Description copied from interface: IndicesClusterStateService.AllocatedIndex

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

Specified by:

updateMetadata in interface IndicesClusterStateService.AllocatedIndex<IndexShard>

Parameters:

currentIndexMetadata - the current index metadata

newIndexMetadata - the new index metadata

dateMathExpressionResolverAt

public <,> dateMathExpressionResolverAt()

dateMathExpressionResolverAt

public <,> dateMathExpressionResolverAt(long instant)

getEngineFactory

public final EngineFactory getEngineFactory()

clearCaches

public boolean clearCaches(boolean queryCache,
 boolean fieldDataCache,
 ... fields)

Clears the caches for the given shard id if the shard is still allocated on this node
