Function Documentation

bool check_depends ( const rapidjson::Value &  depends_json, std::vector< DependsOutcome > &  outcomes, JsonRes &  json_res  )

noexcept

Checks the dependency status of an action

Parameters

[in]	depends_json	(possibly) dependent action
[in]	outcomes	the current stack of previously obtained outcomes
[in]	json_res	the response body, as JSON

Returns

true if the dependency chain is holding, false if broken

template<typename Hdl >

void handle_depends	(	const rapidjson::Value &	json_req,
		JsonRes &	json_res,
		Hdl &&	hdl
	)

Calls an action handler on all actions which dependency chain is holding

Template Parameters

Hdl

(deduced)

Parameters

[in]	json_req	the JSON array of actions to be performed
[in]	json_res	the response body, as JSON
[in]	hdl	the action handler; callable of signature DependsOutcome(const rapidjson::Value&)
