Detailed Description

Resolves trade status transitions via the FSM.

Given an activity_type_code and the trade's current status_id, determines the resulting status_id by looking up the FSM transition linked to the activity type. Throws std::logic_error if the transition is not allowed from the current status.

Member Function Documentation

resolve_status()

boost::uuids::uuid resolve_status ( context  ctx, const std::string &  activity_type_code, std::optional< boost::uuids::uuid >  current_status_id  )

static

Resolves the new status_id for a trade.

Given an activity_type_code and the trade's current status_id (std::nullopt for brand-new trades not yet in the database), returns the resulting status_id after applying the FSM transition linked to the activity type.

If the activity type has no linked FSM transition, the current status_id is returned unchanged (nil UUID for new trades).

Exceptions

std::invalid_argument	if the activity_type_code is unknown.
std::logic_error	if the transition is invalid from the current status.
