Class RootFlattenedFromKeyedFieldData

java.lang.Object

org.elasticsearch.index.mapper.flattened.RootFlattenedFromKeyedFieldData

All Implemented Interfaces:

IndexFieldData<LeafFieldData>

public final class RootFlattenedFromKeyedFieldData
extends Object
implements IndexFieldData<LeafFieldData>

Field data implementation for the root flattened field on indices that no longer write root doc values. Derives root values by reading the keyed doc values column and stripping the key prefix from each entry, with deduplication.

Method Details

getFieldName

public String getFieldName()

Description copied from interface: IndexFieldData

The field name.

Specified by:

getFieldName in interface IndexFieldData<LeafFieldData>

getValuesSourceType

getValuesSourceType in interface IndexFieldData<LeafFieldData>

sortField

public org.apache.lucene.search.SortField sortField(Object missingValue,
 MultiValueMode sortMode,
 IndexFieldData.XFieldComparatorSource.Nested nested,
 boolean reverse)

Description copied from interface: IndexFieldData

Returns the SortField to use for sorting.

Specified by:

sortField in interface IndexFieldData<LeafFieldData>

load

public LeafFieldData load(org.apache.lucene.index.LeafReaderContext context)

Description copied from interface: IndexFieldData

Loads the atomic field data for the reader, possibly cached.
