Method Details

parseCreateField

protected void parseCreateField(DocumentParserContext context)
                         throws IOException

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

Overrides:

parseCreateField in class MetadataFieldMapper

Throws:

IOException

fieldType

public DocCountFieldMapper.DocCountFieldType fieldType()

Overrides:

fieldType in class FieldMapper

contentType

protected String contentType()

Specified by:

contentType in class FieldMapper

field

public static org.apache.lucene.index.IndexableField field(int count)

The field made by this mapper to track the doc count.

syntheticSourceSupport

protected FieldMapper.SyntheticSourceSupport syntheticSourceSupport()

Description copied from class: FieldMapper

Returns implementation of synthetic source support for the mapper.
By default (meaning FieldMapper.SyntheticSourceSupport.Fallback), an exact full copy of parsed field value is stored separately and used for synthetic source.

Field mappers must override this method if they provide a more efficient field-specific implementation of synthetic source.

Overrides:

syntheticSourceSupport in class MetadataFieldMapper

Returns:

FieldMapper.SyntheticSourceMode

leafLookup

public static org.apache.lucene.index.PostingsEnum leafLookup(org.apache.lucene.index.LeafReader reader)
                                                       throws IOException

The lookup for loading values.

Throws:

IOException
