Class template slot

boost::slot — Pass slots as function arguments, and associate tracked objects with a slot.

Synopsis

template<typename Signature,   // Function type R (T1, T2, ..., TN)
         typename SlotFunction = function<Signature> > 
class slot : public slotN<R, T1, T2, ..., TN, SlotFunction> {
public:
  // construct/copy/destruct
  template<typename F> slot(const F &);
  template<typename Func, typename Arg1, typename Arg2, ..., typename ArgN> 
    slot(Func, Arg1, Arg2, ..., ArgN);
};

Description

Class template slot is a thin wrapper around the numbered class templates slot0, slot1, etc. It accepts a function type with N arguments instead of N separate arguments, and derives from the appropriate slotN instantiation.

All functionality of this class template is in its base class slotN.

slot public construct/copy/destruct

  1. template<typename F> slot(const F & f);
    Effects:

    Passes argument to the base type slotN constructor.

    		 
  2. template<typename Func, typename Arg1, typename Arg2, ..., typename ArgN> 
  slot(Func f, Arg1 a1, Arg2 a2, ..., ArgN aN);
    Effects:

    Syntactic sugar for bind() when the constructor is passed more than one argument. As if: slot(boost::bind(f, a1, a2, ..., aN))
