Constructor Detail

MapperService

public MapperService(IndexSettings indexSettings,
                     IndexAnalyzers indexAnalyzers,
                     NamedXContentRegistry xContentRegistry,

                     Supplier<QueryShardContext> queryShardContextSupplier)

Method Detail

hasNested

public boolean hasNested()

getIndexAnalyzers

public IndexAnalyzers getIndexAnalyzers()

getNamedAnalyzer

public NamedAnalyzer getNamedAnalyzer(String analyzerName)

documentMapperParser

public DocumentMapperParser documentMapperParser()

parseMapping

public static Map<String,Object> parseMapping(NamedXContentRegistry xContentRegistry,
                                                    String mappingSource)
                                             throws Exception

Parses the mappings (formatted as JSON) into a map

Throws:

Exception

updateMapping

public boolean updateMapping(IndexMetaData currentIndexMetaData,
                             IndexMetaData newIndexMetaData)
                      throws IOException

Update mapping by only merging the metadata that is different between received and stored entries

Throws:

IOException

merge

public void merge(Map<String,Map<String,Object>> mappings,
                  MapperService.MergeReason reason)

merge

public void merge(IndexMetaData indexMetaData,
                  MapperService.MergeReason reason)

merge

public DocumentMapper merge(String type,
                            CompressedXContent mappingSource,
                            MapperService.MergeReason reason)

parse

public DocumentMapper parse(String mappingType,
                            CompressedXContent mappingSource,
                            boolean applyDefault)
                     throws MapperParsingException

Throws:

MapperParsingException

documentMapper

public DocumentMapper documentMapper()

Return the document mapper, or null if no mapping has been put yet.

documentMapper

public DocumentMapper documentMapper(String type)

Return the DocumentMapper for the given type. By using the special "_default_" type, you can get a DocumentMapper for the default mapping.

isMappingSourceTyped

public static boolean isMappingSourceTyped(String type,
                                           Map<String,Object> mapping)

Returns true if the given mappingSource includes a type as a top-level object.

isMappingSourceTyped

public static boolean isMappingSourceTyped(String type,
                                           CompressedXContent mappingSource)

getTypeForUpdate

public String getTypeForUpdate(String type,
                               CompressedXContent mappingSource)

If the _type name is _doc and there is no _doc top-level key then this means that we are handling a typeless call. In such a case, we override _doc with the actual type name in the mappings. This allows to use typeless APIs on typed indices.

resolveDocumentType

public String resolveDocumentType(String type)

Resolves a type from a mapping-related request into the type that should be used when merging and updating mappings. If the special `_doc` type is provided, then we replace it with the actual type that is being used in the mappings. This allows typeless APIs such as 'index' or 'put mappings' to work against indices with a custom type name.

documentMapperWithAutoCreate

public DocumentMapperForType documentMapperWithAutoCreate(String type)

Returns the document mapper created, including a mapping update if the type has been dynamically created.

fullName

public MappedFieldType fullName(String fullName)

Returns the MappedFieldType for the give fullName. If multiple types have fields with the same full name, the first is returned.

simpleMatchToFullName

public Set<String> simpleMatchToFullName(String pattern)

Returns all the fields that match the given pattern. If the pattern is prefixed with a type then the fields will be returned with a type prefix.

fieldTypes

public Iterable<MappedFieldType> fieldTypes()

Returns all mapped field types.

getObjectMapper

public ObjectMapper getObjectMapper(String name)

unmappedFieldType

public MappedFieldType unmappedFieldType(String type)

Given a type (eg. long, string, ...), return an anonymous field mapper that can be used for search operations.

indexAnalyzer

public Analyzer indexAnalyzer()

searchAnalyzer

public Analyzer searchAnalyzer()

searchQuoteAnalyzer

public Analyzer searchQuoteAnalyzer()

close

public void close()
           throws IOException

public static String[] getAllMetaFields()

reloadSearchAnalyzers

public List<String> reloadSearchAnalyzers(AnalysisRegistry registry)
                                   throws IOException
