Method Details

fieldType

public DenseVectorFieldMapper.DenseVectorFieldType fieldType()

Overrides:

fieldType in class FieldMapper

parsesArrayValue

public boolean parsesArrayValue()

Description copied from class: FieldMapper

Whether this mapper can handle an array value during document parsing. If true, when an array is encountered during parsing, the document parser will pass the whole array to the mapper. If false, the array is split into individual values and each value is passed to the mapper for parsing.

Overrides:

parsesArrayValue in class FieldMapper

parse

public void parse(DocumentParserContext context)
           throws IOException

Description copied from class: FieldMapper

Parse the field value using the provided DocumentParserContext.

Overrides:

parse in class FieldMapper

Throws:

IOException

parseCreateField

protected void parseCreateField(DocumentParserContext context)

Description copied from class: FieldMapper

Parse the field value and populate the fields on DocumentParserContext.doc(). Implementations of this method should ensure that on failing to parse parser.currentToken() must be the current failing token

Specified by:

parseCreateField in class FieldMapper

contentType

protected String contentType()

Specified by:

contentType in class FieldMapper

getMergeBuilder

public FieldMapper.Builder getMergeBuilder()

Description copied from class: FieldMapper

Returns a FieldMapper.Builder to be used for merging and serialization Implement as follows: return new MyBuilder(simpleName()).init(this);

Specified by:

getMergeBuilder in class FieldMapper

doValidate

public void doValidate(MappingLookup mappers)

Overrides:

doValidate in class FieldMapper

getKnnVectorsFormatForField

public org.apache.lucene.codecs.KnnVectorsFormat getKnnVectorsFormatForField()

Returns:

the custom kNN vectors format that is configured for this field or null if the default format should be used.
