Boost C++ Libraries

...one of the most highly regarded and expertly designed C++ library projects in the world. — Herb Sutter and Andrei Alexandrescu, C++ Coding Standards

Class template signal

Class template signal

boost::signal — Safe multicast callback.

Synopsis

template<typename Signature,   // Function type R (T1, T2, ..., TN)
Â Â Â Â Â Â Â Â Â typename Allocator = std::allocator<void>, 
Â Â Â Â Â Â Â Â Â typename Combiner = last_value<R>, 
Â Â Â Â Â Â Â Â Â typename Group = int, 
Â Â Â Â Â Â Â Â Â typename GroupCompare = std::less<Group>, 
Â Â Â Â Â Â Â Â Â typename SlotFunction = function<Signature> > 
class signal : public signalN<R, T1, T2, ..., TN, Combiner, Group, GroupCompare, SlotFunction>
{
public:
Â Â // construct/copy/destruct
Â Â signal(const combiner_type& = combiner_type(), 
Â Â Â Â Â Â Â Â Â const group_compare_type& = group_compare_type());
};

Description

Class template signal is a thin wrapper around the numbered class templates signal0, signal1, etc. It accepts a function type with N arguments instead of N separate arguments, and derives from the appropriate signalN instantiation.

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

`signal` construct/copy/destruct

signal(const combiner_type& combiner = combiner_type(), 
Â Â Â Â Â Â Â const group_compare_type& compare = group_compare_type());

Effects: Initializes the base class with the given combiner and comparison objects.
