public class MetaJoinFieldMapper extends FieldMapper
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.-
