考虑到下面第一个代码片段中的代码 C++,我得到了第二个片段中指示的编译错误。看起来我在遍历向量实例时做错了。你能告诉我如何克服这些编译问题吗?谢谢。代码中标记了第 171 行。
片段 1(代码)
#include <string>
#include <vector>
#include <iterator>
class VipAddressSetEntity : BaseEntity
{
public:
VipAddressSetEntity() : BaseEntity() { }
VipAddressSetEntity(std::string &uuid, std::string &name) : BaseEntity(uuid, name) { }
VipAddressSetEntity(const VipAddressSetEntity ©in)
{
setUUID(copyin.getUUID());
setName(copyin.getName());
std::vector<VipAddressEntity>::iterator iter;
/* LINE 171 is the following*/
for( iter = copyin.mVipAddressList.begin(); iter != copyin.mVipAddressList.end(); iter++ )
{
addVipAddress(*iter);
}
}
VipAddressSetEntity operator = (const VipAddressSetEntity &rhs)
{
setUUID(rhs.getUUID());
setName(rhs.getName());
std::vector<VipAddressEntity>::iterator iter;
for( iter = rhs.mVipAddressList.begin(); iter != rhs.mVipAddressList.end(); iter++ )
{
addVipAddress(*iter);
}
return *this;
}
void addVipAddress(VipAddressEntity &entity)
{
mVipAddressList.push_back(entity);
}
VipAddressEntity & getVipAddress(std::string uuid)
{
std::vector<VipAddressEntity>::iterator iter;
for( iter = mVipAddressList.begin(); iter != mVipAddressList.end(); iter++ )
{
if(iter->getUUID() == uuid)
{
return *iter;
}
}
return NULL;
}
const std::vector<VipAddressEntity>& getVipAddressList() const { return mVipAddressList; }
private:
std::vector<VipAddressEntity> mVipAddressList;
};
