I'm trying to make use of type erasure for fsm based on suggestion from an earlier mail thread

but hitting compilation errors. Can you pls help?

while the any works as expected for push back e.g for vector (bottom of email) it doesnt work for MSM..

BOOST_TYPE_ERASURE_MEMBER((has_process_event), process_event, 1)

typedef any<has_process_event<HandledEnum(Event1 const &)>, _self&> any_fsm;

struct AnyFSM

{

  AnyFSM(any_fsm afsm_) : _afsm(afsm_) {}

  void process(Event1& e) { _afsm.process_event(e); }

  any_fsm _afsm;

};

TestFSM test;

test.start();

AnyFSM(test);

test.process(Event1());

test.cpp:47:43: error: 'Event1' does not refer to a value

typedef any<has_process_event<HandledEnum(Event1 const &)>, _self&> any_fsm;

BOOST_TYPE_ERASURE_MEMBER((has_push_back), push_back, 1)

typedef any<has_push_back<void(int)>, _self&> any_container;

void append_many(any_container container) {

    for(int i = 0; i < 10; ++i)

        container.push_back(i);

}

struct AnyContainer

{

  AnyContainer(any_container cont_) : _cont(cont_) {}

  void append() {append_many(_cont); }

 any_container _cont;

};

AnyContainer m(v);

    m.append();

    for(auto i : v)

      {

      std::cout << i << std::endl;

      }

Thanks
