- All Implemented Interfaces:
Iterable<Mapper>,ToXContent,ToXContentFragment
Mapper that is used to map existing fields in legacy indices (older than N-1) that
the current version of ES can't access anymore. Mapping these fields is important
so that the original mapping can be preserved and proper exception messages can
be provided when accessing these fields.
