談一下信號分發器的作用及實現方法，信號分發實現

信號分發器在很多游戲項目中都有使用，是一種典型的觀察者模式。在游戲編程中，客戶端的繪制往往需要靠邏輯數據來驅動，繪制通過監聽信號等待邏輯的通知。當然了，邏輯模塊跟邏輯模塊相互之間的通知也可以使用信號。這種編程模式能夠簡化模塊之間的通信問題，不需要引用煩人的指針調用，導致指針滿屏飛的情況。C++惡心的地方就是在大型項目中，指針相當多。

那邊，實現一個信號分發器需要哪些功能呢？我們知道，所謂的信號通知，無非就是函數調用。監聽一個信號，其本質上就是綁定一個指針，這個問題的難點在於函數指針是各式各樣的，那麼我們怎麼樣來管理這些指針呢？畢竟我們是想通過一個類似list的集合來保存這些指針。有的人可能會想到用同一種list保持同一種指針，因為一個信號也許只對應一種函數簽名,如果你采用了這種方法，那麼很不幸告訴你，你實現起來會困難重重。要是在Java上，這個問題很好解決，因為JAVA上所有的引用類型對象都自動繼承自Object對象。在C++上，解決這個問題一有兩種方法：1是把所有的指針轉換成int數值，這個能解決指針存問題。2是借用函數包裝。這兩種方法中，方法1顯的很粗糙，無法實現類型安全檢查；方法2就顯示的很優雅，而且能在編譯時期進行接口信號是否匹配問題的檢查。那麼接下來我們的討論將以方法2為准，來講解一個實現。

上面的指針保存問題是實現信號分發器遇到第一個要解決的問題。第二個問題就是，采用函數包裝這種方式，為了方便函數調用，我們需要對參數進行序列化。

以下是一個信號分發器的實現原理的大體流程：

1.綁定一個信號，即有一個類似這樣的結構: std::map<int,std::list<func_ptr>>, 將函數指針放入信號對應的函數指針集中。

2.對這個信號進行通知，即通知這個信號找到對應的std::list<func_ptr>，然後將傳遞的參數進行序列化，將之傳送到相應的處理例程，由相應的處理例程對參數進行反序列化，解析出各個參數，遍歷std::list<func_ptr>集合調用函數。

至此過程完畢，沒錯，就是這麼簡單。

總結一下需要用到的相應的庫：一個類型萃取庫traits,一個序列化庫serialization，一個函數包裝庫callhelper。如果看過我之前博文的同學，那麼就會注意到在下的小心機了，這三個庫在下都一一按順序發布過了。

接下來簡單介紹下這個信號分發器的相應用法及主要功能。

這個庫實現的主要三個優點：

1. 在調一次信號時只會產生一次序列化和一次反序列化消耗，這個應該是不可避免。大家要是有好的方法歡迎來討論長知識（我見過會產生一次序列化和n次反序列化的信號庫實現，原來公司項目中使用的一次實現就是這樣，這個其實是沒有必要的）。

2. 這個信號庫允許一個信號對應多個不同簽名的調用接口，至少實戰中到底有沒有這個必要，這裡暫時不討論。

3. 支持引用類型及指針類型的傳遞。

一個額外的支持就是這個庫可以增加信號過濾器的，這個過濾器代碼我就不貼出了。

接下來貼代碼，說的再多，不如看代碼：

#include "signalcall2/signalcall2.hpp"

// 聲明一個信號並綁定一類簽名
DECLARE_SIGNAL2(SIG_TEST,1,void(std::string&))
// 使用同一個信號並綁定別一類簽名
VALIDE_SIGNAL(SIG_TEST,void(std::string ,int))

int main()
{
    // 定義一個類對象
    Stu stu;

    // 定義一個信號分發器對象
    signalcall::signalcall2 sig; // 你可能會好奇為什麼是signalcall2，因為我還實現過一個版本1，這是版本2，版本1並不具備版本2的優雅性。
    // 綁定信號
    // 前兩個接口是同一類型的簽名
    sig.bindSignal<SIG_TEST>(show);
    sig.bindSignal<SIG_TEST>(&stu,&Stu::show);
    // 這個接口是不同的簽名
    sig.bindSignal<SIG_TEST>(show2);

    // sig.bindSignal<SIG_TEST>(show3); // 當試圖綁定show3函數，會編譯不過，因為並沒指聲明信號SIG_TEST對應void(int)類型簽名

    // 通知信號
    std::string str = "你好，我是字符串！";
    // 只會通知到void(std::string&)類型的接口
    sig.signal<SIG_TEST>(str);

    // 只會通知到void(std::string,int)類型的接口
    sig.signal<SIG_TEST>("我是void(std::string,int)類型的接口",1);

　　　// 解綁信號相應的接口
　　 sig.unbindSignal<SIG_TEST>(show);

　　 // 或者解決信號的所有接口
　　 sig.unbindAllSignal();

return 0;
}

輸出結果:
