Function signature for handlers connecting the signal.


Member Function Documentation

template<typename R , typename Marshal = class DefaultMarshal<R>>
Connection scim::Signal0< R, Marshal >::connect ( SlotType slot  )  [inline]

Connect a slot to the signal.

Parameters:
slot - a slot of type Slot0<R>.
Returns:
a connection object.

The returned connection object can be used alter or change the connection.

template<typename R , typename Marshal = class DefaultMarshal<R>>
SlotType* scim::Signal0< R, Marshal >::slot (  )  [inline]

Returns a slot for this signal.

Returns:
a new slot of type Slot0<R>.

The returned slot can be passed to another signal allowing the other signal to call this signal when it gets emitted.

Referenced by scim::Signal0< void, IgnoreMarshal >::emit(), and scim::Signal0< R, Marshal >::emit().

template<typename R , typename Marshal = class DefaultMarshal<R>>
R scim::Signal0< R, Marshal >::emit (  )  [inline]

Emit the signal.

Returns:
the value returned by the signal handler.

Calls every slot connected to this signal, in order of connection.
