class documentation

class prefix_anon_map(Dict[str, str]): (source)

A map that creates new keys for missing key access. Considers keys of the form "<ident> <name>" to produce new symbols "<name>_<index>", where "index" is an incrementing integer corresponding to <name>. Inlines the approach taken by :class:`sqlalchemy.util.PopulateDict` which is otherwise usually used for this type of operation.
