IndexNumericFieldData

public IndexNumericFieldData()

Method Details

getNumericType

public abstract IndexNumericFieldData.NumericType getNumericType()

The numeric type of this number.

sortField

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

Returns the SortField to used for sorting. Values are casted to the provided targetNumericType type if it doesn't match the field's numericType.

sortRequiresCustomComparator

protected abstract boolean sortRequiresCustomComparator()

Does sortField(org.elasticsearch.index.fielddata.IndexNumericFieldData.NumericType, java.lang.Object, org.elasticsearch.search.MultiValueMode, org.elasticsearch.index.fielddata.IndexFieldData.XFieldComparatorSource.Nested, boolean) require a custom comparator because of the way the data is stored in doc values (true) or are the docs values stored such that they can be sorted without decoding (false).

sortField

public final 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<LeafNumericFieldData>

 @Nullable
 Object missingValue,
 MultiValueMode sortMode,
