Detailed Description

Generic enum↔string (and optional external key) mappers built on DynamicRegistry.

This header provides two templated mapper classes:

• GenericMapperNoExt: bridges an enum type and its string names, with support for dynamic aliases and user-defined symbols.
• GenericMapperWithExt: extends the above with an additional "external key" (e.g. FLHA indices, integer codes, etc).

Both mappers are parameterized by:

• Tag : a tag type used to instantiate SymbolId<Tag> (strong-typed string id),
• EnumT : the enum type being mapped,
• MapFn : a function pointer returning a const std::map<EnumT,std::string>& with the builtin mapping (legacy/static map),
• ExtFn : (for GenericMapperWithExt) a function pointer returning const std::map<EnumT,ExternalKey>& for the external mapping.

The internal DynamicRegistry uses case-insensitive normalization via normalize_key(), so lookups are case-insensitive and aliases can be added at runtime without interfering with builtin names.

Typedef Documentation

IdOf

template<class Tag >

using IdOf = SymbolId<Tag>

Convenience alias for the identifier type associated with a given tag.

Template Parameters

Tag	Tag used for SymbolId instantiation.

Function Documentation

nk()

std::string nk ( std::string_view  s )

inline

Shortcut helper to normalize a string_view into a canonical key.

This simply forwards to normalize_key().

Parameters

s	Input string_view.

Returns

Normalized string.
