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:Definestheentrypointfortheconsoleapplication.

#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_SStringnumber_;
};
