c++之sigslot库

关于

本文演示环境： win10 + VS2017

1. demo

#include <iostream>
#include "sigslot.h"

using namespace sigslot;

class Switch
{
public:
	signal0<>  clicked;
};

class Light : public has_slots<>
{
public:
	void on()
	{
		std::cout << "the light is on\n";
	}
};

int main(int argc, char *argv[])
{
	Light light;
	Switch sw;
	sw.clicked.connect(&light, &Light::on);

	sw.clicked.emit();

	system("pause");

	return 0;
}

2.编译出错

下载原版的sigslot.h文件编译出错：

.......

3.正确编译

替换下面的代码 到 sigslog.h中，编译成功，编译及运行结果：

4. sigslot.h

修改后的sigslot.h说明如下：

// Libjingle specific:
// This file has been modified such that has_slots and signalx do not have to be
// using the same threading requirements. E.g. it is possible to connect a
// has_slots<single_threaded> and signal0<multi_threaded_local> or
// has_slots<multi_threaded_local> and signal0<single_threaded>.
// If has_slots is single threaded the user must ensure that it is not trying
// to connect or disconnect to signalx concurrently or data race may occur.
// If signalx is single threaded the user must ensure that disconnect, connect
// or signal is not happening concurrently or data race may occur.

//
//      #define switches
//          SIGSLOT_PURE_ISO            - Define this to force ISO C++ compliance. This also disables
//                                        all of the thread safety support on platforms where it is
//                                        available.
//
//          SIGSLOT_USE_POSIX_THREADS   - Force use of Posix threads when using a C++ compiler other than
//                                        gcc on a platform that supports Posix threads. (When using gcc,
//                                        this is the default - use SIGSLOT_PURE_ISO to disable this if
//                                        necessary)
//
//          SIGSLOT_DEFAULT_MT_POLICY   - Where thread support is enabled, this defaults to multi_threaded_global.
//                                        Otherwise, the default is single_threaded. #define this yourself to
//                                        override the default. In pure ISO mode, anything other than
//                                        single_threaded will cause a compiler error.
//
//      PLATFORM NOTES
//
//          Win32                       - On Win32, the WIN32 symbol must be #defined. Most mainstream
//                                        compilers do this by default, but you may need to define it
//                                        yourself if your build environment is less standard. This causes
//                                        the Win32 thread support to be compiled in and used automatically.
//
//          Unix/Linux/BSD, etc.        - If you're using gcc, it is assumed that you have Posix threads
//                                        available, so they are used automatically. You can override this
//                                        (as under Windows) with the SIGSLOT_PURE_ISO switch. If you're using
//                                        something other than gcc but still want to use Posix threads, you
//                                        need to #define SIGSLOT_USE_POSIX_THREADS.
//
//          ISO C++                     - If none of the supported platforms are detected, or if
//                                        SIGSLOT_PURE_ISO is defined, all multithreading support is turned off,
//                                        along with any code that might cause a pure ISO C++ environment to
//                                        complain. Before you ask, gcc -ansi -pedantic won't compile this
//                                        library, but gcc -ansi is fine. Pedantic mode seems to throw a lot of
//                                        errors that aren't really there. If you feel like investigating this,
//                                        please contact the author.
//
//
//      THREADING MODES
//
//          single_threaded             - Your program is assumed to be single threaded from the point of view
//                                        of signal/slot usage (i.e. all objects using signals and slots are
//                                        created and destroyed from a single thread). Behaviour if objects are
//                                        destroyed concurrently is undefined (i.e. you'll get the occasional
//                                        segmentation fault/memory exception).
//
//          multi_threaded_global       - Your program is assumed to be multi threaded. Objects using signals and
//                                        slots can be safely created and destroyed from any thread, even when
//                                        connections exist. In multi_threaded_global mode, this is achieved by a
//                                        single global mutex (actually a critical section on Windows because they
//                                        are faster). This option uses less OS resources, but results in more
//                                        opportunities for contention, possibly resulting in more context switches
//                                        than are strictly necessary.
//
//          multi_threaded_local        - Behaviour in this mode is essentially the same as multi_threaded_global,
//                                        except that each signal, and each object that inherits has_slots, all
//                                        have their own mutex/critical section. In practice, this means that
//                                        mutex collisions (and hence context switches) only happen if they are
//                                        absolutely essential. However, on some platforms, creating a lot of
//                                        mutexes can slow down the whole OS, so use this option with care.
