PARSER

public static final FieldMapper.TypeParser PARSER

Method Details

fieldType

public KeywordFieldMapper.KeywordFieldType fieldType()

Overrides:

fieldType 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

indexScriptValues

protected void indexScriptValues(SearchLookup searchLookup,
 org.apache.lucene.index.LeafReaderContext readerContext,
 int doc,
 DocumentParserContext documentParserContext)

Description copied from class: FieldMapper

Run the script associated with the field and index the values that it emits This method should only be called if FieldMapper.hasScript() has returned true

Overrides:

indexScriptValues in class FieldMapper

Parameters:

searchLookup - a SearchLookup to be passed the script

readerContext - a LeafReaderContext exposing values from an incoming document

doc - the id of the document to execute the script against

documentParserContext - the ParseContext over the incoming document

contentType

protected String contentType()

Specified by:

contentType in class FieldMapper

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

doValidate

public void doValidate(MappingLookup lookup)

Overrides:

doValidate in class FieldMapper

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 FieldMapper

Returns:

FieldMapper.SyntheticSourceMode

syntheticFieldLoader

public SourceLoader.SyntheticFieldLoader syntheticFieldLoader(String fullFieldName,
 String leafFieldName)
