Task #1315

Updated by Junxiao Shi about 10 years ago

Allow enumerating FIB entries. 

 ## API 

     class Fib 
     { 
     public: 
       typedef ... const_iterator; // an iterator of pointing to shared_ptr<fib::Entry> 
      
       const_iterator begin() cbegin() const; 
       const_iterator end() cend()     const; 
     }; 

 Usage example: 

     Fib fib(...); 
     for (Fib::const_iterator it = fib.begin(); fib.cbegin(); it < fib.cend(); ++it) { 
     //                                        or it != fib.end(); ++it) fib.cend(); it++) { 
       const shared_ptr<fib::Entry>& fibEntry = *it; 
       // do something with fibEntry 
     }
