java.lang.Object

org.elasticsearch.index.mapper.blockloader.docvalues.BlockDocValuesReader.DocValuesBlockLoader

org.elasticsearch.index.mapper.blockloader.docvalues.AbstractBytesRefsFromOrdsBlockLoader

org.elasticsearch.index.mapper.blockloader.docvalues.BytesRefsFromOrdsBlockLoader

All Implemented Interfaces:

BlockLoader

public class BytesRefsFromOrdsBlockLoader
extends AbstractBytesRefsFromOrdsBlockLoader

Loads keyword style fields that are stored as a lookup table and ordinals. See also BytesRefsFromCustomBinaryBlockLoader for wildcard style (i.e. non-ordinal encoded multivalued) and BytesRefsFromBinaryBlockLoader for histogram style (i.e. non-ordinal single valued).

Method Details

singletonReader

protected BlockLoader.ColumnAtATimeReader singletonReader(TrackingSortedDocValues docValues)

Specified by:

singletonReader in class AbstractBytesRefsFromOrdsBlockLoader

sortedSetReader

protected BlockLoader.ColumnAtATimeReader sortedSetReader(TrackingSortedSetDocValues docValues)

Specified by:

sortedSetReader in class AbstractBytesRefsFromOrdsBlockLoader

supportsOrdinals

public boolean supportsOrdinals()

Description copied from interface: BlockLoader

Does this loader support loading bytes via calling BlockLoader.ordinals(org.apache.lucene.index.LeafReaderContext).

Specified by:

supportsOrdinals in interface BlockLoader

Overrides:

supportsOrdinals in class BlockDocValuesReader.DocValuesBlockLoader

ordinals

public org.apache.lucene.index.SortedSetDocValues ordinals(org.apache.lucene.index.LeafReaderContext context)
                                                    throws IOException

Description copied from interface: BlockLoader

Load ordinals for the provided context.

Specified by:

ordinals in interface BlockLoader

Overrides:

ordinals in class BlockDocValuesReader.DocValuesBlockLoader

Throws:

IOException

toString

public String toString()

Overrides:

toString in class Object

rowStrideReader

public BlockLoader.RowStrideReader rowStrideReader(CircuitBreaker breaker,
 org.apache.lucene.index.LeafReaderContext context)
                                            throws IOException

Description copied from interface: BlockLoader

Build a row-by-row reader. May return null if the underlying storage prefers to be loaded column-at-a-time. Callers should try BlockLoader.columnAtATimeReader(org.apache.lucene.index.LeafReaderContext) first, only falling back to this if BlockLoader.columnAtATimeReader(org.apache.lucene.index.LeafReaderContext) returns null. This may not return null if BlockLoader.columnAtATimeReader(org.apache.lucene.index.LeafReaderContext) does.

Specified by:

rowStrideReader in interface BlockLoader

Overrides:

rowStrideReader in class BlockDocValuesReader.DocValuesBlockLoader

Throws:

IOException
