Method Summary

Modifier and Type	Method	Description
MappedFieldType.CollapseType	collapseType()	Returns the collapse type of the field CollapseType.NONE means the field can'be used for collapsing.
DocValueFormat	docValueFormat(String format, ZoneId timeZone)	Return a DocValueFormat that can be used to display and parse values as returned by the fielddata API.
IndexFieldData.Builder	fielddataBuilder(String fullyQualifiedIndexName, Supplier<SearchLookup> searchLookup)	Return a fielddata builder for this field
IndexNumericFieldData.NumericType	numericType()
Number	parsePoint(byte[] value)
Function<byte[],Number>	pointReaderIfPossible()	If the field supports using the indexed data to speed up operations related to ordering of data, such as sorting or aggs, return a function for doing that.
org.apache.lucene.search.Query	rangeQuery(Object lowerTerm, Object upperTerm, boolean includeLower, boolean includeUpper, SearchExecutionContext context)	Same as SimpleMappedFieldType.rangeQuery(Object, Object, boolean, boolean, ShapeRelation, ZoneId, DateMathParser, SearchExecutionContext) but without the trouble of relations or date-specific options.
org.apache.lucene.search.Query	termQuery(Object value, SearchExecutionContext context)	Generates a query that will only match documents that contain the given value.
org.apache.lucene.search.Query	termsQuery(Collection<?> values, SearchExecutionContext context)	Build a constant-scoring query that matches all values.
String	typeName()	Returns the name of this type, as would be specified in mapping properties
ValueFetcher	valueFetcher(SearchExecutionContext context, String format)	Create a helper class to fetch field values during the FetchFieldsPhase.
Object	valueForDisplay(Object value)	Given a value that comes from the stored fields API, convert it to the expected type.

NumberFieldType

public NumberFieldType(String name,
 NumberFieldMapper.NumberType type)

Method Details

typeName

public String typeName()

Description copied from class: MappedFieldType

Returns the name of this type, as would be specified in mapping properties

Specified by:

typeName in class MappedFieldType

numericType

public IndexNumericFieldData.NumericType numericType()

termQuery

public org.apache.lucene.search.Query termQuery(Object value,
 SearchExecutionContext context)

Description copied from class: MappedFieldType

Generates a query that will only match documents that contain the given value. The default implementation returns a TermQuery over the value bytes, boosted by MappedFieldType.boost().

Specified by:

termQuery in class MappedFieldType

termsQuery

public org.apache.lucene.search.Query termsQuery(Collection<?> values,
 SearchExecutionContext context)

Description copied from class: MappedFieldType

Build a constant-scoring query that matches all values. The default implementation uses a ConstantScoreQuery around a BooleanQuery whose BooleanClause.Occur.SHOULD clauses are generated with MappedFieldType.termQuery(java.lang.Object, org.elasticsearch.index.query.SearchExecutionContext).

Overrides:

termsQuery in class MappedFieldType

rangeQuery

public org.apache.lucene.search.Query rangeQuery(Object lowerTerm,
 Object upperTerm,
 boolean includeLower,
 boolean includeUpper,
 SearchExecutionContext context)

Description copied from class: SimpleMappedFieldType

Same as SimpleMappedFieldType.rangeQuery(Object, Object, boolean, boolean, ShapeRelation, ZoneId, DateMathParser, SearchExecutionContext) but without the trouble of relations or date-specific options.

Overrides:

rangeQuery in class SimpleMappedFieldType

pointReaderIfPossible

public Function<byte[],Number> pointReaderIfPossible()

Description copied from class: MappedFieldType

If the field supports using the indexed data to speed up operations related to ordering of data, such as sorting or aggs, return a function for doing that. If it is unsupported for this field type, there is no need to override this method.

Overrides:

pointReaderIfPossible in class MappedFieldType

Returns:

null if the optimization cannot be applied, otherwise a function to use for the optimization

fielddataBuilder

public IndexFieldData.Builder fielddataBuilder(String fullyQualifiedIndexName,
 Supplier<SearchLookup> searchLookup)

Description copied from class: MappedFieldType

Return a fielddata builder for this field

Overrides:

fielddataBuilder in class MappedFieldType

Parameters:

fullyQualifiedIndexName - the name of the index this field-data is build for

searchLookup - a SearchLookup supplier to allow for accessing other fields values in the context of runtime fields

valueForDisplay

public Object valueForDisplay(Object value)

Description copied from class: MappedFieldType

Given a value that comes from the stored fields API, convert it to the expected type. For instance a date field would store dates as longs and format it back to a string in this method.

Overrides:

valueForDisplay in class MappedFieldType

valueFetcher

public ValueFetcher valueFetcher(SearchExecutionContext context,
 String format)

Description copied from class: MappedFieldType

Create a helper class to fetch field values during the FetchFieldsPhase.

New field types must implement this method in order to support the search 'fields' option. Except for metadata fields, field types should not throw UnsupportedOperationException since this could cause a search retrieving multiple fields (like "fields": ["*"]) to fail.

Specified by:

valueFetcher in class MappedFieldType

docValueFormat

public DocValueFormat docValueFormat(String format,
 ZoneId timeZone)

Description copied from class: MappedFieldType

Return a DocValueFormat that can be used to display and parse values as returned by the fielddata API. The default implementation returns a DocValueFormat.RAW.

Overrides:

docValueFormat in class MappedFieldType

parsePoint

public Number parsePoint(byte[] value)

collapseType

public MappedFieldType.CollapseType collapseType()

Description copied from class: MappedFieldType

Returns the collapse type of the field CollapseType.NONE means the field can'be used for collapsing.

Overrides:

collapseType in class MappedFieldType

Returns:

collapse type of the field
