How to pass a sc_event as parameter without pointers?

[SiGa]

I have a class with an sc_event which should be readable and writeable through getter and setter methods.

class IntWithEvent {
 private:
	sc_event _ev_wr;
	sc_event _ev_trigger;
public:
 	const sc_event& get_write_event() const {
		return _ev_wr;
	}
  
 	const sc_event& get_trigger_event() const {
		return _ev_trigger;
	}
  
	void set_trigger_event(sc_event &ev) const {
		_ev_trigger = ev; // E0349	no operator "=" matches these operands
	}
}

 

Writing the getters was no problem. However the setter throws me an error of no matching assignment operator. 

Do I need to store a pointer to a sc_event and then set the pointer to the address of the parameter? It doesn't give me compile errors like this.

class IntWithEvent {
 private:
	sc_event _ev_wr;
	sc_event *_ev_trigger;
public:
 	const sc_event& get_write_event() const {
		return _ev_wr;
	}
  
 	const sc_event& get_trigger_event() const {
		return *_ev_trigger;
	}
  
	void set_trigger_event(sc_event *ev) {
		_ev_trigger = ev; 
	}
}

I was taught to avoid pointers where I can. Is there a way to avoid the pointers?

Looks like XY problem to me. If you need pointer to event, use pointer.
