ores.cpp.asset_class.authorities
Table of Contents
The C++ projection of the catalogue's mapping. asset_class_for_authority
takes the authority text a datum or an index names.
An authority the mapping leaves empty – correlation and generic – is
simply absent from the function, so it answers std::nullopt for it.
asset_class_codes carries the taxonomy's own codes, in display order, so a
test-data generator that must emit a code the catalogue holds reads it rather
than restating the list.
The header is written into ores.marketdata.api, beside the datum model
whose authorities it maps. The build already links ores.refdata.api into
ores.marketdata.core, so the dependency direction is unchanged.
See the Template variable reference for the complete list of available variables and their semantics.
