c++ - 使用 C++ 检查并将数据添加到 protobuff

Question

message HealthOccurrenceCount
{
    required int64 HealthID=1; 
    required int32 OccCount=2; 
    optional bytes wci=3;
}

我想添加基于的数据HealthID；如果HealthID已输入，则程序不应添加新条目，而应仅增加现有条目的OccCount.

HealthOccurrenceCount objHelthOccCount;
if(objHelthOccCount.healthid() == healthID) // Is this right or do I need to iterate all the nodes?
{
    occCount++;  
    objHelthOccCount.set_occcount(occCount);  
}
else       
    occCount = 1;   

这段代码是正确的还是我应该转换HealthID成字符串？

生成的代码：

// required int64 HealthID = 1;
inline bool has_healthid() const;
inline void clear_healthid();
static const int kHealthIDFieldNumber = 1;
inline ::google::protobuf::int64 healthid() const;
inline void set_healthid(::google::protobuf::int64 value);

Answer 1

HealthOccurrenceCount objHelthOccCount;
if(objHelthOccCount.has_healthid())
{
    occCount++;  
    objHelthOccCount.set_occcount(occCount);  
}
else       
    occCount = 1;
