public class MetaJoinFieldMapper
extends org.elasticsearch.index.mapper.MetadataFieldMapper
Simple field mapper hack to ensure that there is a one and only ParentJoinFieldMapper per mapping. This field mapper is not used to index or query any data, it is used as a marker in the mapping that denotes the presence of a parent-join field and forbids the addition of any additional ones. This class is also used to quickly retrieve the parent-join field defined in a mapping without specifying the name of the field.
