Method Summary

Modifier and Type	Method	Description
java.util.function.Function<java.lang.String,java.util.function.Predicate<java.lang.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.

MapperRegistry

public MapperRegistry(java.util.Map<java.lang.String,Mapper.TypeParser> mapperParsers,
                      java.util.Map<java.lang.String,MetadataFieldMapper.TypeParser> metadataMapperParsers,

Method Detail

getMapperParsers

public java.util.Map<java.lang.String,Mapper.TypeParser> getMapperParsers()

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

getMetadataMapperParsers

public java.util.Map<java.lang.String,MetadataFieldMapper.TypeParser> getMetadataMapperParsers()

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

isMetaDataField

public boolean isMetaDataField(java.lang.String field)

Returns true if the provide field is a registered metadata field, false otherwise

getFieldFilter

public java.util.function.Function<java.lang.String,java.util.function.Predicate<java.lang.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.
