Method Details

getFieldName

String getFieldName()

The field name.

getValuesSourceType

ValuesSourceType getValuesSourceType()

The ValuesSourceType of the underlying data. It's possible for fields that use the same IndexFieldData implementation to have different ValuesSourceTypes, such as in the case of Longs and Dates.

load

FD load(org.apache.lucene.index.LeafReaderContext context)

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

loadDirect

FD loadDirect(org.apache.lucene.index.LeafReaderContext context)
       throws Exception

Loads directly the atomic field data for the reader, ignoring any caching involved.

Throws:

Exception

sortField

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

Returns the SortField to use for sorting.

newBucketedSort

BucketedSort newBucketedSort(BigArrays bigArrays,
 @Nullable
 Object missingValue,
 MultiValueMode sortMode,
 IndexFieldData.XFieldComparatorSource.Nested nested,
 SortOrder sortOrder,
 DocValueFormat format,
 int bucketSize,
 BucketedSort.ExtraData extra)

Build a sort implementation specialized for aggregations.
