c++ - ブーストの非同期状態マシン

Question

asynchronous_state_machine の processor_handle からスケジューラへの参照を取得することは可能ですか?

コード：

struct A {
    A(sc::fifo_scheduler<>::processor_handle& h):player_ref(h){}
    sc::fifo_scheduler<>::processor_handle& player_ref;
    void a_func(){
       //I have to send event to player, but don't have scheduler
       scheduler.queue_event( player_ref_, ... ); //?
    }
};

sc::fifo_scheduler<> scheduler( true );
sc::fifo_scheduler<>::processor_handle player = 
    scheduler1.create_processor< Player >();
A a(player);
