Subject: [Boost-users] [MSM] templated state machine generates many errors when a state is derived from msm::front::exit_pseudo_state<event>
From: Richard Hodges (hodges.r_at_[hidden])
Date: 2016-08-10 18:26:52
I just wanted to check that there was not something obvious I am doing wrong here:
relevant parts:
the exit state (defined outside the state machine)
struct QueryGood {
QueryGood(query_complete const& r)
: result(r.result)
{}
// note: universal converting constructor
template<class T>
QueryGood(const T&) {}
pkt result;
};
template<class Environment>
struct dns_query_
: msm::front::state_machine_def<dns_query_<Environment>>
{
// error happens when I derive from exit_pseudo_state. deriving from msmf::state<> eliminates all errors
struct Complete : msm::front::exit_pseudo_state<QueryGood> // msmf::state<>
{ ... };
...
// transition table:
struct transition_table :
mpl::vector<
// Start Event Next Action Guard
// +--------------+---------------------+--------------+---------------------+----------------------+
msmf::Row < NotStarted , RestartQuery , Querying , msmf::none , msmf::none >,
msmf::Row < Complete , RestartQuery , Querying , msmf::none , msmf::none >,
msmf::Row < Error , RestartQuery , Querying , msmf::none , msmf::none >,
msmf::Row < Querying , query_timeout , Error , NotifyUpdate , IsCurrentEvent >,
msmf::Row < Querying , RestartQuery , Querying , msmf::none , msmf::none >,
msmf::Row < Querying , query_error , Error , NotifyUpdate , IsCurrentEvent >,
msmf::Row < Querying , query_complete , Complete , NotifyUpdate , IsCurrentEvent >
// +--------------+---------------------+--------------+---------------------+----------------------+
>
{};
};
