SortedNumericIndexFieldData

public SortedNumericIndexFieldData(String fieldName,
 IndexNumericFieldData.NumericType numericType)

Method Details

getFieldName

public final String getFieldName()

Description copied from interface: IndexFieldData

The field name.

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.

sortRequiresCustomComparator

protected boolean sortRequiresCustomComparator()

Description copied from class: IndexNumericFieldData

Does IndexNumericFieldData.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).

Specified by:

sortRequiresCustomComparator in class IndexNumericFieldData

dateComparatorSource

protected IndexFieldData.XFieldComparatorSource dateComparatorSource(Object missingValue,
 MultiValueMode sortMode,
 IndexFieldData.XFieldComparatorSource.Nested nested)

Overrides:

dateNanosComparatorSource

protected IndexFieldData.XFieldComparatorSource dateNanosComparatorSource(Object missingValue,
 MultiValueMode sortMode,
 IndexFieldData.XFieldComparatorSource.Nested nested)

Overrides:

getNumericType

public IndexNumericFieldData.NumericType getNumericType()

Description copied from class: IndexNumericFieldData

The numeric type of this number.

Specified by:

loadDirect

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

Description copied from interface: IndexFieldData

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

Throws:

Exception

load

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

Description copied from interface: IndexFieldData
