Method Details

indexAnalyzers

public Map<String,NamedAnalyzer> indexAnalyzers()

Overrides:

indexAnalyzers 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

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

Specified by:

parseCreateField in class FieldMapper

Throws:

IOException

contentType

protected String contentType()

Specified by:

contentType in class FieldMapper

fieldType

public TextFieldMapper.TextFieldType fieldType()

Overrides:

fieldType in class FieldMapper

createPhraseQuery

public static org.apache.lucene.search.Query createPhraseQuery(org.apache.lucene.analysis.TokenStream stream,
 String field,
 int slop,
 boolean enablePositionIncrements)
                                                        throws IOException

Throws:

IOException

createPhrasePrefixQuery

public static org.apache.lucene.search.Query createPhrasePrefixQuery(org.apache.lucene.analysis.TokenStream stream,
 String field,
 int slop,
 int maxExpansions,
 String prefixField,
 IntPredicate usePrefixField)
                                                              throws IOException

Throws:

IOException

doXContentBody

protected void doXContentBody(XContentBuilder builder,
 ToXContent.Params params)
                       throws IOException

Overrides:

doXContentBody in class FieldMapper

Throws:

IOException

syntheticSourceMode

protected FieldMapper.SyntheticSourceMode syntheticSourceMode()

Description copied from class: FieldMapper

Specifies the mode of synthetic source support by the mapper.
This is used to determine if a field mapper has support for constructing synthetic source. In case it doesn't (meaning FieldMapper.SyntheticSourceMode.FALLBACK), we will store raw source data for this field as is and then use it for synthetic source.

Field mappers must override this method if they provide a custom implementation of FieldMapper.syntheticFieldLoader() in order to use a more efficient field-specific implementation.

Overrides:

syntheticSourceMode in class FieldMapper

Returns:

FieldMapper.SyntheticSourceMode

syntheticFieldLoader

public SourceLoader.SyntheticFieldLoader syntheticFieldLoader()

Description copied from class: FieldMapper

Mappers override this method with native synthetic source support. If mapper does not support synthetic source, it is generated using generic implementation in DocumentParser.parseObjectOrField(org.elasticsearch.index.mapper.DocumentParserContext, org.elasticsearch.index.mapper.Mapper) and ObjectMapper.syntheticFieldLoader().

Overrides:

syntheticFieldLoader in class FieldMapper

Returns:

implementation of SourceLoader.SyntheticFieldLoader
