ACE_Hash_Map的使用示例

一位网友说他不能在ACE中正常地使用嵌套使Hash_Map,我写下下面的代码作了简单测试,发现在ACE使用Hasp_Map还是可以的.

//  TestHaspMap.cpp : Defines the entry point for the console application.

#include  " stdafx.h "
#include  " ACE/Basic_Types.h "
#include  " ACE/Map_Manager.h "
#include  " ACE/SString.h "
#include  " ACE/Log_Msg.h "
#include  " ACE/Null_Mutex.h "

class  PhoneNumber
{
public :
    PhoneNumber( const   char *  number):number_(number)
    {

    }
     const   char *  getNumber( void )
    {
         return  number_.c_str();
    }
private :
    ACE_SString  number_; 
};
