Method Details

getFieldName

public String getFieldName()

Description copied from interface: IndexFieldData

The field name.

Specified by:

getFieldName in interface IndexFieldData<T>

getValuesSourceType

public ValuesSourceType getValuesSourceType()

Description copied from interface: IndexFieldData

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.

Specified by:

getValuesSourceType in interface IndexFieldData<T>

load

public SourceValueFetcherIndexFieldData.SourceValueFetcherLeafFieldData<T> load(org.apache.lucene.index.LeafReaderContext context)

Description copied from interface: IndexFieldData

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

Specified by:

load in interface IndexFieldData<T>

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<T>

newBucketedSort

public BucketedSort newBucketedSort(BigArrays bigArrays,
 Object missingValue,
 MultiValueMode sortMode,
 IndexFieldData.XFieldComparatorSource.Nested nested,
 SortOrder sortOrder,
 DocValueFormat format,
 int bucketSize,
