org.elasticsearch.index.mapper.FieldAliasMapper

All Implemented Interfaces:

java.lang.Iterable<Mapper>, ToXContent, ToXContentFragment

public final class FieldAliasMapper
extends Mapper

A mapper for field aliases. A field alias has no concrete field mappings of its own, but instead points to another field by its path. Once defined, an alias can be used in place of the concrete field name in search requests.

merge

public Mapper merge(Mapper mergeWith)

Description copied from class: Mapper

Return the merge of mergeWith into this. Both this and mergeWith will be left unmodified.

Specified by:

merge in class Mapper

updateFieldType

public Mapper updateFieldType(java.util.Map<java.lang.String,MappedFieldType> fullNameToFieldType)

Description copied from class: Mapper

Update the field type of this mapper. This is necessary because some mapping updates can modify mappings across several types. This method must return a copy of the mapper so that the current mapper is not modified.

Specified by:

updateFieldType in class Mapper

iterator

public java.util.Iterator<Mapper> iterator()

toXContent

public XContentBuilder toXContent(XContentBuilder builder, ToXContent.Params params) throws java.io.IOException

Throws:

java.io.IOException
