MapperRegistry

public MapperRegistry(Map<String,Mapper.TypeParser> mapperParsers,

 Map<String,MetadataFieldMapper.TypeParser> metadataMapperParsers,
 Function<String,Predicate<String>> fieldFilter)

Method Details

getMapperParser

public Mapper.TypeParser getMapperParser(String type,
 IndexVersion indexVersionCreated)

Return a mapper parser for the given type and index creation version.

getRuntimeFieldParsers

public Map<String,RuntimeField.Parser> getRuntimeFieldParsers()

getMetadataMapperParsers

public Map<String,MetadataFieldMapper.TypeParser> getMetadataMapperParsers(IndexVersion indexCreatedVersion)

Return a map of the meta mappers that have been registered. The returned map uses the name of the field as a key.

getFieldFilter

public Function<String,Predicate<String>> getFieldFilter()

Returns a function that given an index name, returns a predicate that fields must match in order to be returned by get mappings, get index, get field mappings and field capabilities API. Useful to filter the fields that such API return. The predicate receives the field name as input arguments. In case multiple plugins register a field filter through MapperPlugin.getFieldFilter(), only fields that match all the registered filters will be returned by get mappings, get index, get field mappings and field capabilities API.
