Hi Christophe,
In case a class is derived from the msm::back::state_machine class and used
with the favor_compile_time policy I get the following error:
*No member function 'process_any_event' declared*
Please consider the following code snippets to get more details:
*// MasterStateMachine.hpp*
struct Master_: mgp_state_machine_def {
// ...
}
*class MasterStateMachine : public msm::back::state_machine{
public:
MasterStateMachine () { // some stufff };
}
*// MasterStateMachine.cpp*
#include "MasterStateMachine.hpp"
BOOST_MSM_BACK_GENERATE_PROCESS_EVENT(MasterStateMachine)
Why does the compiler complains although the class MasterStateMachine
inherits the "process_any_event" method from the
*msm::back::state_machine* back-end?
The point of matter is the
*BOOST_MSM_BACK_GENERATE_PROCESS_EVENT(MasterStateMachine)* macro. In case
it is uncomment, everythin works fine, but unfortunately without the support
of the favor_compile_time policy.
Background: I need to derive the class *MasterStateMachine * from the the
mentioned back-end as singleton semantic has to be added to the
*MasterStateMachine * class. *Not using* the favor_compile_policy is not a
option!
I have already tried to overload the *process_any_event* method in the
derived "MasterStateMachine" class to comply with the compilers needs:
class MasterStateMachine : public msm::back::state_machine{
private:
static MasterStateMachine *m_Instance;
// Constructor to avoid instantiation from the outside
MasterStateMachine() {};
// Constructor to avoid copy-constructing
MasterStateMachine(const MasterStateMachine&) {}
// Constructor to avoid assignation
MasterStateMachine& operator = (const MasterStateMachine&) { return *this;
}
~MasterStateMachine() {};
public:
static MasterStateMachine* getInstance();
static void release();
msm::back::HandledEnum process_any_event(const boost::any & evt) {
return this->process_any_event(evt);
}
};*
Unfortunately the error remains!
Does anybody ;) have a clue?
Thanks in advanced!
Regards,
Rafael
